Seven Segment LCDs? Answered

Http://i00.i.aliimg.com/photo/v0/325133078/7_segment_LCD_panel.jpg Has anyone had any luck hooking up seven segment lcds to their arduino's? These have 4 seven segment digits, a :, and an am/pm display. They have less than 28 pins.

How to I display voltage on a 7 segment display?

Okay, I've never actually come across this before or needed to do this but now i come to it, i realise I am really lost to it. What i need to do is display a 3 digit (hundreds eg. 342) number on three 7 segment displays. So pretty much I just need a 3 digit voltage read-out to be incorporated into a portable design. I've been looking around and have come across the Analog to Digital converters, and understand how they work, but I'm not sure how to incorporate them or to put it to any use. So if anyone knows or has a schematic or any information I could work off, please help. :)ThanksPyroten

7 segment led display driver help?

7 segment sed driver/decoder circuit helpEMAIL FLAGIve looked all over, and have already tried 3 circuits, but none work. They have either the wrong ic, wrong led display, etc. So, I want to make a circuit that, by using a decoder, I can flip 4 dip switches and make the display make certain numbers. I have a 7447 ic, common cathode led display, but I can only either find a circuit with a 7447 and a common anode, or a circuit with a common cathode but a different decoder (a latch/decoder/driver). Here is the first site I tried:http://www.allaboutcircuits.com/vol_6/chpt_7/9.htmlAnd when I finally flip the switches, nothing happens even though I made it exactly as shown. But it has a CMOS, so thats probably a big problem. I also tried this site:http://www.atilim.edu.tr/~hkar/lab5.htmBut it has a common anode, and when I tried it it didnt work. I have exactly ELS321HDB. And I have a power unit that can go from 5 - 18 volts. Can anyone show me how to make this? Im not too good yet at reading circuit diagrams, because I seem to make it way more complex then it should be.

Fixing a 5 character seven segment display clock

This is a count up race clock that fell due to high winds and has stopped working. It is a springco athletics model 2710A. I have already tried respecting and reconnecting all the non soldered pieces of this display. The main chip on the board is a PIC16F887 with 20 pins. Each display is connected by a single ribbon cable with 20 pins and there are jumpers on each display labeled 1-6(presumably for the character placement in the display). If I cannot find a way to fix the current hardware I would like to replace the control board with an arduino that can do the same thing but I do not know how to wire the display to the arduino nor what model to use. Any suggestions are welcomed.

Read from a 7-segment display LCD

Hello everyone. Suppose you have some device with a numeric LCD display with some 7-segment digits (i.e. a digital scale), and you want to hack it in order to read out electronically (for example with an rs232 connection), while preserving functionality of the thing. How you would do that?

new to arduino, want to run a dual display for 2 sensors

I'm new to the Arduino community.  wanting to set up a dual radar setup with 2 ultrasonic sensors,  (Ultrasonic Sensor Module HC-SR04), and outputting to a pair of 7 segment displays ( two 7 segment displays each).  I've found a code to do a single could use a lot of help to output two at the same time, basically 2 lanes without 2 units.  im using an arduino mega, ordered a unor3 and hopefully it can be made to run on one or the other. code is as follows: /* HC-SR04 Sensor    The circuit:     * VCC connection of the sensor attached to +5V     * GND connection of the sensor attached to ground     * TRIG connection of the sensor attached to digital pin 2     * ECHO connection of the sensor attached to digital pin 4  */    /*  This is a radar ping sensor that calcultates the speed of an  object traveling away or towards the sensor.

Dear Instructables, how would i go about creating a 3 digit up counter that reacted to 3 buttons of different values?

Basically i'm designing and making a scoreboard for a rugby match for an a-level course. I'll explain the buttons of different values first, in rugby (for those who don't know) there are 3 different ways that the score can increase 2 points (conversion), 3 points (penalty, drop goal) and 5 points (try). I already know how to make a circuit to increase in 1's but i wasn't sure if you could do it with 3 different values in the same circuit. I was thinking of using a 4024 seven bit counter connected to a bcd to led decoder then to 7 segment led displays. is there anything out there which could make my job easier or do you have any advice or could you help me?

YY:DDD:HH:MM:SS Countup Clock

I was looking to make a countup clock that would be able to count off time in seconds, minutes, hours, days, and years using seven segment displays. I have yet to be able to find an instructable like this. I imagine it would be very similar to a normal clock; however I do not know enough about electronics to be able to modify the standard clock instructables to be able to make my own.  The only way I know to do this with the knowledge I currently have is to make a mini PC and that would be cost prohibitive as well as overpowered.   The idea came up because I have my one year anniversary approaching and I figured it would be neat to have a clock whose sole purpose is to give an exact time count of being married.  I played around with the idea of having the clock play a song or display something any time a new year was added, but I figured for now to just stick to the basics.   If anyone knows of an instructable that fits this idea or is willing to make one/point me in the right direction here, that would be fantastic.

Maximum/minimum ampere input in a circuit, help needed.

To start of my question im going to say i don't know a lot of electronics and that I am norwegian( so please excuse typos in english) :) I have not done many major projects inside the field of electronics other than making a lightbulb light up. using a battery and to wires.. But I am very interseted in electonics ad think it is very exiting to read about.  As my first "real" project i decided to make a "lie detector", altough it is mostly just a circuit that measures the resistance in your skin and makes a beeping sound after how much resistance your skin has( Dry skin = low resistance vs wet/sweaty skin = much resistance). AND I DID IT! i made it work, and i was so proud! Then I realized that it was actually kinda lame and the beebing noise was wery annoying. So I decided to make a display that displayed a value after how much resistance your skin held. I managed to make a seven segment display from scratch. But now I am stuck... You see the circuit gives an output of amps so it will output more amps on wet skin than on dry skin. But I have to "program"  the circuit to make the numbers on my display change. I want preferably to be able to do this without any IC's. So my question is there possible to make a circuit that will allow current to pass through one circuit, but if the current is high enough it will take another way? I tried to use diffrent resistors, but I didnt take into count that electricity only takes the road of least resistance no matter..

Any PIC Experts out there?

Can somebody help? I have a few PIC16F628, ISD2532 sound chips and 4-digit seven segment LED displays with MM5450 chips from some old laser-gaming boards that I’d like to do something with but have got completely baffled by the data sheets and the complications of PIC programming. Basically, what I’d like to do is create a ‘dummy bomb’ as a present for my local gaming field along the lines of:- • Have a hex keypad enter an ‘unlock code’. Display and save that code • Use the hex keypad to input the time to start counting down from (Minutes & Seconds). Display and lock in that time • Have a button start to ‘arm’ the bomb and start decrementing the time and display it • When the timer reaches 00.00 then ‘fire’ the sound effect in the MM5450 and have an output go low for triggering something else • The device can be ‘defused’ by entering the correct code (equal to that previously stored) or by cutting the ‘correct’ wire – other wires triggering the device. It would seem to me that the ‘wire cutting’ scenario could be accomplished by using tied inputs – one changing state defuses, the others trigger the device. In an ideal world, the device would have 2 operating modes – timer and non-timer, the non-timer mode allowing for the device to be triggered by trip-wire, breaking an IR beam, a ‘hit’ from a gaming gun, etc. In a perfect world, it could also send a 56Khz IR data stream to ‘kill’ all the gaming guns within range but I don’t know the coding for that data stream and it may be in the realms of fantasy anyway… I don’t have a PIC programmer yet but they don’t seem difficult to build or hard to find – only having a laptop means USB though and that does limit things… I can do all the wiring and packaging but is there somebody who could help me out with the programming and/or general advice? Thanks Duncan

Global Warming Experiment #1

(I slightly changed the instructable into a forum topic and an instructable)The Instructable Half"Global Warming" Experiment #1:As you can tell by my quotes around "Global Warming", I personally don't believe that this theory is happening. Theres facts I can use to prove this. However, even I believe that no matter how you put it, there's going to be some bias. Also facts are boring :PSo, what I have planned, is to do a series of experiments on what global warming might cause if it were real.I'm doing this because I've heard people claim some extraordinary things, which based on data won't happen.I could post an instructable with a bunch of facts, and I might. But for now, I want to set up a couple collaborative experiments. One reason I want collaboration is I'm biased. The other, is so you can't complain about my methods.I haven't done the experiment yet, I really don't know if this will help, or hurt, my case.The experiment is to determine if "global warming" could melt glaciers, thus cooling the ocean. Notice here I'm assuming global warming is happening. It isn't. But when people make claims on the news and stuff, they are assuming that too.Please comment if you would like to change my methodology, OR you want to do the experiment.I'm going to describe how the Instructable (and hopefully the rest in the series) will work.1) I, or anyone, proposes a framework for an experiments and writes up an Instructable. (Will be referred to as "I" in the following steps)2) I monitor the suggestions, editing and fixing as needed. After about a week or so, I go onto step 3.3) I preform the experiment to the best of my ability, and write up an additional 2 steps.3a) The first outlines my changes. This could mean I didn't have a 4x8 loaf pan, and I had to use a 3x8. Or it was plastic. Whatever. These small details are important3b) The second outlines the data and conclusion. This may have images of the experiment, graphs, tables, sensor data, Whatever. I also make a note of my previous bias.4) Wait for more people to run through the experiment, adding them as collaborators.5) Write up a conclusion to everything, OR do some more investigating.Its not that bad, however the whole process might take a few weeks. (I don't know)Scientific MethodThere are seven steps to the Scientific Method, which we will follow:1. Define the question2. Gather information and resources3. Form hypothesis4. Perform experiment and collect data5. Analyze data6. Interpret data and draw conclusions that serve as a starting point for new hypotheses7. Publish results(Thanks Wikipedia!)#1 was done in the introduction.#2 I've already done, however you only have to look into data you'll need during the procedure.#3 I've done it, but I'm not telling you (I don't want a bias, even though I've hinted towards my guess)#4 - We're going to expand this out. More later!#5 and #6 sort of come together in this format, will be done as we go along.#7 is done as we go!Okay, #4. Remember back to High School, remember Lab Reports? Well basically there will be a step for each segments (leaving some out). We sort of do this already in most instructables "What will happen", "What you need", "How you do it"; this time more formally. Due to Lab Reports being unstandardized, I'm breaking it down into:IntroductionMaterialsProcedureDataIts shorter than your average one, due to the fact in Data, you have hypothesis and stuff I don't want to reveal yet ;-)The following is the framework, you can also see my instructable:(This is a framework, remember. Its not supposed to be "done" and perfect)Materials*Large basin of some sorts.*Water*Ice*Lamp + Light bulbs (100W & 40W)*ThermometerProcedure1) Fill large basin/pan with water.2) Take and record standing temperature of water.3) Add ice off to one side of the pan.4) Take temp. of water every five minutes until it starts to level out, at least 4 readings.5) Replace water, and repeat steps 2&36) Shine lamp w/ 40W bulb off to the non-ice side of the pan, but allowing some light & warmth to reach the ice. (Roughly 20-35%)7) Repeat steps 4&58) Repeat step 6 with a 100W bulbTake pictures throughout!What now?Okay, I'll be updating this with your comments over the next week or so. If somethings wrong with it, POINT IT OUT!!! I'm going to add my thoughts in as well. (I still feel its missing some things, I can't put my fingers on them, though!)
