Binary Arduino Alarm Clock HELP!

I am currently working on THIS INSTRUCTABLE: I have had to modify the libraries to work with IDE 1.0 and newer because this was written 5 years ago. I'm using a push button momentary switch instead of the capacitive sensor for the snooze button. I've got everything working except for the Alarm/snooze. For some reason, the speaker is constantly beeping a high, then low tone, as though the snooze button is being held down, even when I completely disconnect the snooze button from the clock. Can anyone give me any ideas how to fix this problem? Here is my modified button code: void update_buttons_state() {   hour_button_state    = digitalRead(hour_button_pin);   minute_button_state  = digitalRead(minute_button_pin);   setTime_button_state = digitalRead(setTime_button_pin);   setAlarm_button_state = digitalRead(setAlarm_button_pin);   snooze_button_state = digitalRead(snooze_button);     } // "INTERNAL" VARIABLES FOR BUTTONS FUNCTION: boolean first_time_hour = true;   // these are used to make sure that the hours boolean first_time_minute = true; // and minutes only is increased once every keypress. unsigned long snooze_button_timer; // used to keep track of how long the snooze button has                                    // been held down. when the button has been held down                                    // a certain amount of time, the alarm will be turned                                    // of completely. void buttons() {   // LOW == button pressed   // HIGH == button released   // (this is because pullup resistors is used)     // Decide if we should set time or alarm:   // (this also makes the display show the alarm time)   if(setAlarm_button_state==LOW) // LOW = Set time   {     hours_p = &alarm;_hours;     minutes_p = &alarm;_minutes;   } else if(setTime_button_state==LOW) // LOW = Set Alarm   {     hours_p = &hours;     minutes_p = &minutes;   }   // If hour button is pressed, increase hours:   if(hour_button_state==LOW && first_time_hour) // only increase the hours once   {                                             // every button press.     if(*hours_p < 23)       (*hours_p)++;     else       *hours_p = 0;         first_time_hour = false;          }   else if(hour_button_state==HIGH)   {     first_time_hour = true; // reset when button is released,   }                         // so that the next press will be registerd.     // If minute button is pressed, increase minutes:   if(minute_button_state==LOW && first_time_minute) // only increase the minutes   {                                                 // once every button press.     if(*minutes_p < 59)       (*minutes_p)++;     else       *minutes_p = 0;           first_time_minute = false;   }   else if(minute_button_state==HIGH)   {     first_time_minute = true; // reset when button is released,   }                           // so that the next press will be registerd.     if(snooze_button_state==LOW)   {     if(signal_on)     {       // set the time when the alarm signal will start again,       // this will give 10 minutes snooze:       if(minutes<50)       {         snooze_off_minutes = minutes+10;         snooze_off_hours = hours;       }       else       {         snooze_off_minutes = minutes - 50;         snooze_off_hours = hours + 1;       }       snooze_on = true;       signal_on = false;     }     // if the snooze button has been held down for more than 3 seconds turn off/on the alarm     if((millis() - snooze_button_timer) > 5000)     {       if(alarm_on) // if on, turn off       {         signal_on = false;         alarm_on = false;         snooze_on = false;         // play tone so the user know the alarm turned off:, 100);       }       else if(alarm_on==false) // if off, turn on       {         alarm_on = true;         // play tone so the user know the alarm turned off:, 100);       }       //reset the snooze button timer       snooze_button_timer=millis();     }       }   else   {     //reset the snooze button timer     snooze_button_timer=millis();   } }

Logic circuit to generate and convert 3 bits parallel binary code into series for subsequent transmission ? Answered

A project I am working on has 6 water sensors placed at different altitudes inside a tank.I've developed a circuit to assign 3 bit binary codes to each of the sensor and then transmit it wirelessly.I've attached the truth table and the binary functions that yield the desired output, as a picture.Please refer to it and check if it looks alright to you.Keep in mind that the sensors output '0' (ground) when idle and '1' (Positive) when active.  Also, the sensors are so placed that sensor 2 won't get activated unless sensor 1 is activated ,sensor 3 unless sensor 2 is activated and so on..I.e,when the sixth (last) sensor is activated ,all the other sensors would be active too.So,the truth table contains just the possible combinations. A,B,C,D,E and F are the sensors(bottom to top) X,Y and Z will be fed into a binary encoder ic,whose output will be transmitted. Surfing the web,I realised that logical high and low can also be set using pull up and pull down resistors .I would appreciate it if someone could enlighten me on how this is done.(Explaining with reference to my circuit will be the best way)

10 bit to 7 segments

Hi everyone!! I'm posting because i need help! I want to make a 10 bit to 7 segments schematic/circuit. I need to just convert 10 bit binary to decimal.. In my idea i have 10 switches and every one of them represents a number in decimal. for example when i put ON my first switch from the right i want that in the 7 segments appears the number "1" and for example when i switch ON the last switch from the left it appears "512" and if all of them are ON appears 1023. So i have 10 ON/OFF switch and 4 (7 segment) display. I have a PIC programmer, so if anyone can help by hardware or software it would be great. Thank you very much!!!

How do I preset a 4029 counter?

Hi all. I am having trouble finding how to preset the minimum output of a 4029. Meaning that I want it to start at an output of 5 (0101) and count up to 15 (1111) and then have it start counting at 5 again. My project is an ASCII counter to check that the ASCII displays with 7 bit binary inputs that I have are functioning correctly and I want to use the 4029 as my input. The problem that I am having is possably misinterpreting the data sheets but is seems that in order to preset the input, the preset pin has to be HI but to run, it has to be LO. Does this mean that I have to set the prest HI, input my preset value of 5, and then bring it LO again to run?   Any help would be appreciated. Thank you much in advance.

Binary Clock-LED not working, why?

I followed about everything on this plan But Instead I used a 555 in astable to run about 1Hz. I already tested the 555 on a individual led and it worked. Now I finally completed my work and my leds are not lighting up. I believe I should remove the resistor since the max output of the counter is only about 4mA so I would be limiting my current, ALOT. The thing is, I tested every LEDS with a multimeter both including resistors and not and they are all lighting up all fine, but when I install my counter, see that the led are not working and I try to make a diode test, they doesn't light up at all. I need to remove the counter in order to be able to light them up. What is the solution and why? Is it sinking current? But it design is not to sink, but to source..... Help please, thanks.

Circuitry help needed - microcontroller in binary clock

Ok, so I am currently working on a project which involves some circuitry and programming. I am planning to make a simple binary watch. Now with my current plan I am planning on making 2-3 circuit boards depending on what I can get. The first circuit board will connect the leds for the time read. It will be a standard four column hour and minute binary clock readout. The second board will contain an ATtiny85 microcontroller, a 74HC595 8-bit shift register, two push buttons, two 10k ohm resistors, and four 220 ohm resistor. The third board will be glued to the bottom of the second board for the battery holder and some extra space to add wire tracing. Now I plan to design and etch my own pcb boards and solder them together. Though for the second and third board being glued together would add a bit of thickness so I am wondering if I can buy a dual sided pre-sensitized circuit board to etch?Thes plans are based off the work of another user on here, link to his clock below: Credit to him for this great and simple system. With my very limited knowledge and understanding of circuitry and programming, this is one of the most straightforward clocks I have found. This is general format I will try to follow, though I do wish to make some modifications to the circuit or program based on what is possible with the circuit setup. First I am concerned about the power consumption of the system and how I can reduce the supplied power to make it run on a watch battery and run for about a year if possible or longer. Second I know that adding a crystal oscillator can improve the accuracy of the clock by synchronizing the internal clock on a set frequency. So with that, how would I add a 16 Mhz crystal oscillator to the circuit? The program that is given in the project runs based on the internal 16 Mhz internal clock of the ATtiny85. Third question is what system works best to program the ATtiny85? I have a Raspberry Pi 3B+ and I also have Syper IDE and I am fairly good at programming with python. So could I program the ATtiny85 with my Raspberry pi and use python? Or would I have to use a different board and language to program the micocontroller?

Microcontroller help!

So I'm working on a project to build a binary clock style watch, though I have very limited experience and knowledge about circuitry and microcontrollers. As of right now I have found a relatively simple project on this site I wish to replicate and downsize to fit in the size of a watch. The design of the circuit is based off the layout in this project: I have read up on microcontrollers and microprocessors. I also read some stuff about oscillators and how they can work to essentially synchronize the internal clocks of microcontrollers making them more accurate for clock uses. First is this true that a crystal oscillator can improve the accuracy of a microcontroller? And if so, how could I add a 16.000 Mhz crystal oscillator to the circuit presented above? (I want to use a 16.000 Mhz oscillator because the code written for the microcontroller is based on the 16 Mhz internal clock, so this should line up fine)Thanks if you can answer these questions!

Programming help needed!

So I'm currently working on a project to build a binary clock style watch. I have found a pretty straight forward and simple project to replicate. The project does give a code to upload to an ATtiny85 so that the project will work. Now I noticed that he was programming his ATtiny with an Arduino board and I assume he used a different coding language than python(which is what I am familiar with). Here is the link to the project for more info: I have a Raspberry Pi 3B+, and I have Anaconda, Spyder, and Jupyter on my computer which I have used before to create standalone programs. My question is can I use my raspberry pi to program an ATtiny85 or would I need a different board to program it? And second how simple is it to program the ATtiny?

Program to read/write data on usb?

I am looking for a program or at least how it can be done on visual basic that: allows the user to read incoming serial information and produce outgoing serial information on windows. Example: Write is selected > Baud rate selected > binary data entered Result: serial data is transmitted through the usb port Thanks!

Chords With An Arduino Microcontroller?

Does anyone have any idea as to how I could make more than just one tone with the Arduino Uno? I would like to make chords. I had an idea that you could make octaves with a binary counter that would half the frequency, but you still only get one key at a time (i.e. A, G#, Db, etc...)

Is there a way to decompile iPhone apps? Answered

I was wondering if there was a way to decompile apps on the iPhone that were made by apple (Clock, Calender, Stocks, etc.) in order to get the Obj-C source code (or any editable code if you cant get the Obj-C).  I can ssh into it to get the binaries, but dont know how to decompile them.  any help would be great.  Thanks.

Enough with the 3d printing already

At the start of the "3d printing" was fun now, its just annoying. Every single time I get updates from the site there is at least one in it for 3d printing but more often then not there is two maybe three. Its old news, old hat and now annoying. Is there any way to block subject matter having anything to do with "3d printing" but letting everything else thru?

Logic gate help

I'm attempting to build an binary calculator out of an old iphone box using LED's and such and have a wiring system set up but i need to know how to make/buy some form of "if then else" gate (i.e. if A=1 then B=1 else C=1 and if A=0 then B=0 and C=1). I would love to know if there is some kind of way to do this using transistor logic but anything that works as an "if then else" gate is welcome.

analogue-digital cmos chips? Answered

Is there a chip like the LM3914 that takes an analogue voltage input and turns it into a digital signal? (preferably BCD, but decimal is fine too), but without the inverting output, so I can use it with other CMOS chips? I basically just want a chip that takes an analogue signal, and based on a threshold, divides it up into a decimal (or binary) signal. Specifically, I want to use it with a thermistor and a 7-segment display to make a digital thermometer.

How to write a program to count switch presses for an arduino uno?

Write a program to count switch presses (one complete closing and opening of a switch is one count), and display the count in binary on 4 LEDs. When the count exceeds 1510 (note that a subscript 10 means that the number is decimal, so 1510 is 15 in decimal notation) the displayed count must roll over (all LEDs must go out and the count should begin again at zero).

LED-shirt v2.0 on its way!

Hey Instructablonians! So after thinking about it for a while, I realized that my original Beating Heart T-shirt was a bit.... restrictive... as to what you could display on your glorious torso. As a result, I decided to embark on a journey to make a fully programmable 14X7 LED array display on a t-shit, which I call LED-shirt v2.0! Also, since I was making this portable and re-programmable, I figured that you should be able to go everywhere and still have some nerd "bling", so I included a charlieplexed LED binary clock. I drew up the schematic on eagle, routed the board, etched it, drilled it, stuffed it, programmed the binary clock, then soldered ALL of the crimp beads onto all 91 LEDs and female header (it's got to be detachable). I tried sewing some of the LEDs on via a sewing machine, but I bought the wrong thickness conductive thread, and the machine kept jamming. Then I tried by hand, and it just takes too long v_v. (I'm using Leah Buechley's method)I'm going to order the thinner thread and find someone with a sewing machine they're willing to lend me. Until then, I have this awesome blue binary clock that I can carry around with me!Oh, it's atmega168-based, runs @ 12MHz, and as of now runs off of 3 AA's, but I have plans to make it LI-ion compatible. Also, I have to thank Zach for the idea to make the 14X7 matrix - it's really a demi-charlieplexed 7x7 array.Oh, and if you were wondering, that's an aluminum rod w/ a captive ring next to the battery pack. I love lathes.-Muffin

Can this computer support Windows 7? Answered

Hey, I've been shopping for a new computer and over all of the results, the cheapest most powerful one I've found is the HP Envy H8 with a AMD 6 core processor at 3.8Ghz (4.1 max). I will put my Radeon 7750 into it too. Anyhow, here is the one I want (Hopefully it hasn't sold yet, but there are many people selling it for this price too): So my question is, if I buy the Windows 7 OEM from (Shipped and sold by Amazon), would this system be able to run it correctly? If not, could I make any adjustments to make it run correctly? Thanks! (Hoping to run Battlefield 3, Portal 2, Team Fortress 2, Roblox, Minecraft, Halo Combat Evolved, Grand Theft Auto IV, and Need for Speed World on it at about medium graphics with at least 30-40FPS).

howto make 3d shutter glasses?

I cannot find any instructable on making something like shutter glasses. my idea is: the left-eye image gets a white 10x10px rectangle in the top-left corner of the computer screen, the right-eye image gets a black rectangle. the shutter glasses would have a photoresistor glued (or somehow placed) onto that 10x10px-area for timing. but i don't know how to use that (binary) signal to control the transparency of the 2 LCDs. i don't even know which LCDs to use or where to buy it.

Logic Gate Help Needed Answered

I am building a Binary to Decimal converter and i need help making a flawless AND gate from bipolar-junction transistors. If someone could Send me a link or email me some schematics, I would greatly appreciate it. If you do email the schematics please make sure they are compatible with Eagle. I don't want to use a converter chip because it takes away the fun of the project for me. I have tried all of the common types of AND gate configurations using NPN's (C-fwd B-in E-collect, C-in B-fwd E-Base, Etc.).

Circuitry help needed!

So I'm working on a project to build a binary clock style watch. I have found a fairly simple system to replicate though I plan to downsize the circuit to fit within roughly a 40x40mm area, the height I am not too concerned about right now. Here is the link to the project I plan to replicate: with the circuit presented I plan to break it into two boards(possibly three). The top board would utilize 2.8x3.2mm LED chips and connect them properly for the ATtiny and shift register. The second board would house the resistors, ATtiny, shift register, and buttons. It would connect to the LED board via vertical wires that would pass through the LED board and hold it directly above. On the bottom of the second board would be the battery holder and wires to directly connect the positive and negative leads to the needed inputs from the backside of the board. This would result in the second and third boards being back to back. (And I do plan on designing and etching my own boards for this project)So my questions for you are:I want to add a 16.000 Mhz crystal oscillator to the circuit to increase the accuracy of the internal clock of the ATtiny, so where would I add it in?How could I reduce the output power from the battery to run the system on minimal power so that my battery can last a year or longer?And is there such thing as a dual sided pre-sensitized pcb board I could use to make the circuits?

Advice sought on how to make Plastic mould

I’m trying to repair a folding camping bed. See picsIt has a number of feet and other blocks made of some form of HDPE or similar. I want to recreate these blocks. How can I do so? The material needs to be rigid but not brittle.I can find plaster or gel to make a mould but what material should I use? Is there some sort of binary mixture such as a flexible filler ?I have access to basic tools and power tools but not a lathe nor 3D printingAnother option is to buy a block of HDPE and drill and carve the holes, but where to buy the block (in UK)?

Steampunk Mobile

Some great ideas come from taking a completely new gadget and making it something that looks like, and in this case sort of works like, something from the 19th century. This steampunk cell phone concept has no display. No 3G. No data plan. No games. It doesn't even have a dial pad. You make your calls with binary-coded punch cards, steampunk.All you get in this rugged brown package is an earpiece, (possibly faux) gauges, visible screws, and a spinning number-counter. Oh, and a hole punch every time you want to order a pizza.The project was developed for O2, aiming at the RPG player market (really!). I don't think it works. It would be cool if it did, but I don't think so...UnplggdOriginal designer
