Can anyone help me with data transmission in serial communication through a hub? Answered

I need to write a c code, and using an Arduino uno, I should be able to transmit a short text to a recipient who is also connected to a hub. many other people are also connected to the same hub, but they should not be able to receive my text. Only the intended receiver is supposed to receive my text. As of now, I don't even know how to start the code. Is anyone out there who can help walk me through this project?

attiny85 to control two different jobs through a switch?

What i really want is to piece up 2 sketches together in attiny85 programming,the result is to enable it to be controlled through a switch.the 2 sketched are pretty long.I don't know how bcz i am a newbie in programming.at first i thought of 'Case,break'syntax,but later found it may not suitable. The pins i choose is Pin4(Analog2) physical pin3 of attiny85 to control of WS2812B light strip.another Pin1(PWM)physical Pin6 to control a speaker. #include #include #define PIN 4 Adafruit_NeoPixel strip = Adafruit_NeoPixel(30, PIN, NEO_GRB + NEO_KHZ800); void setup() {     Serial.begin(9600);   strip.begin();   strip.show(); // Initialize all pixels to 'off' } void loop() {     int sensorValue = analogRead(A0);   Serial.println(sensorValue);//Just for the calipration     if(sensorValue > 10)   { rainbowCycle(0); } if(sensorValue >30){ theaterChase(strip.Color(255,0,0),10); theaterChase(strip.Color(255,0,0),10); theaterChase(strip.Color(0,0,255),10); } if(sensorValue >40){   colorWipe(strip.Color(255,0,0),10);   colorWipe(strip.Color(0,255,0),10);   colorWipe(strip.Color(0,0,255),10); } } ============ /* ATtiny85 Speaker */ // constants const int Speaker = 1;             // speaker pin void setup() {   pinMode(Speaker, OUTPUT); void playBeep(void) {     for (int i=0; i < 500; i++)     {       digitalWrite(Speaker, HIGH);       delay(1);       digitalWrite(Speaker, LOW);       delay(1);     } }

Can someone help me code for the bare conductive board?

I recently bought an arduino and bare conductive board and really need help trying to code three things at once. So the idea is to use a servo motor, audio speaker, and lights to go off when in proximity of the electric paint. The project itself is having a mouth open and sounds/ lights come on. From what I can tell I can get the audio with bare conductive board, but not sure how to hardware the servo and the lights on the board either. I can see online its possible to hardware the arduino with a bread board with sensor coding, speakers and lights, but for the audio its beeps. With the bare conductive you get the mp3 storage capacity.

It has only two wires, 3 push buttons and one toggle switch. I do know the input voltage is 5 volt and every button has its own resistor causing different voltages to come out when used. This way the car computer knows what has been pressed. I have 3 switches: 1: Acc (Cruise Control Accelerate speed) 2: Ret (Cruise Control Retrieve speed) 3: Res (Cruise Control Resume from last speed) I have one toggle Switch: Cruisecontrol ON/OFF I want the ON/OFF to toggle a keyboard character "C" when used. I want button 1 to send a "7" I want button 2 to send an "8" I want button 3 to send a "9" The code should pause after each change (no loop). The 10k Restistor is a pull-up resistor for debounce.

Does any one know any good java / c++ / c# tutorials on the net?

I'm looking into coding, but no one happens to do a good tutorial! If some one could post one on Instructables that would be even better. Would any one recommend coding as a job for an up-coming member of society? (I'm not there yet.)

Help with Arduino Coding

Hello. I have recently been interested in coding Arduino and the USAF lets me to launchpads to setup remote cameras that are sound activated for a rocket launch. I was working on designing an Arduino connected to one of the cheap sound detector modules on eBay. The camera would be triggered by a short circuit on the digital end, with the sound module on the analog end. The camera is activated by a short circuit on the shutter release, so I though I would have + going into the camera when sound is activated with the other cables on ground. I just needed someone to check over my coding, as I am debating whether or not to buy an Arduino. No errors appeared on the computer, so I don't know if it will work fine or not                                                                                                                                                                                                                void setup() {}   //Just there as placeholder: void loop()    //To repeat a function of detecting sound: {const int SoundDetectorPin = A2;  //Sound Detector Module located at Analog pin 2:   const int CameraTriggerOutput = 3;  //Dual Trigger Output is located at Digital pin 3: //Following is If functions: if (analogRead(SoundDetectorPin) == LOW) //When power is read, if it is LOW, the trigger detected sound:      digitalWrite(CameraTriggerOutput, HIGH); //Pin 3 is given positive voltage: else {  //If opposite happens:     digitalWrite(CameraTriggerOutput, LOW); //When power is read, if it is HIGH, the trigger is detected nothing and no command is excecuted:    } }

When using PHP, does it matter where you place the code?

Might seem like a silly question but is it better to place all your PHP code at the top of the page, then echo it where you want it to be, or to keep the code all in one spot? For example, Option One: [rest of webpage] Option Two:  echo ' $random_thing'; ?> Hopefully that makes sense...

Request: Non-Alpha Characters in Titles to Designate Awards

Dear Instructables Administration: While downloading Instructables as PDF files, I like to edit the name of the file with the following convention at the end of the title: How_to_Make_Mashed_Potatoes (*++).pdf The part that looks like this (*++) indicates that the instructable has been featured (*) and has been a finalist in 2 contests (++). This lets me peruse my downloaded instructables within a given category (I file them by project type) and find one that is really top-of-the-line at a glance. Would it be possible and/or acceptable to have this sort of suffix automatically added to the title of downloads by the instructable web site? This would save much time and effort for me and anyone else who was interested in this luxurious little feature. Perhaps it could be included as a preference check-box for those who did (or didn't) want this feature enabling them to choose it? Would the code to do this be difficult to implement? I hereby request this feature for pro members! Timothy Nugent

Arduino Coding Question: How do I blink one LED 8 times and then another LED 8 times then repeat?

I'm using two 4017 decade counters to count to 16 and I figure two Arduino outputs would be a good way to go. I want one 4017 to receive 9 pulses then and then wait while the other 4017 receives 9 pulses. (one pulse is a holding position) For the moment I'm just trying to blink one LED 9 times and then another 9 times to represent two separate clock outputs. Here is a diagram: pin 13    1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1, pin 12    0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 0, Start      ------------------------------------------------------------------------------------------------------------ then loop. This is for multiplexing a 16x16 led screen so I don't think I should use the  delay(1000);  command. Each counter needs 9 pulses with the last pulse to the first counter happening simultaneously with the first pulse to the second counter. And similarly the first counter getting its first pulse at the same time as the second counter gets its 9th pulse. Get it?

Anyone interested in making a Video Game?

Hi. I'm looking for a group of people to help me make a Video Game. I have lots of ideas, but the big problem: I have absolutely NO coding, drawing, or music composing skills. I'm looking for people who have those skills, and would like to help out. I live in Canada, but you don't have to live there. I'm good with Skype, or something else. I'm fine with any software. I don't have any money, but I was going to put the games on Kickstarter, and I could pay people off that profit. I have ideas about most genres, like RPG, or action, or even a simulation. One idea is this war game where you command a small army, and attack other people. I can't really explain much, other than you can upgrade your troops, and unlock special troops, like Motherships. Or maybe a tycoon game. I don't really know, I mostly come up with ideas on the spot... So that's all I think i should say. If you need more questions answered about me, just ask.

Redesign instructables to make searching easier and more practical!?!?!?

I'm fairly new to instructables. i've only read about 100 or so and not made any myself. for the most part i can rarely find an instructable that is of high enough quality end-product or end-result for me to commit to making it instead of starting from scratch and designing my own thing, or buying something that has already been produced for a more affordable and higher quality end-product. but there is one huge reason i remain committed and interested in instructables as a website and a community! my dad has a garage full of high-potential junk! now if only there were an easy way for me to search instructables for projects based on my plethora of ingredients (inventory) rather than typing finished project titles or end-result names of creations into the search bar. i understand that this may be extremely hard to do since there may literally be an infinite number of names and objects, not to mention the various languages, misspellings, and misnaming of objects and processes that would need to be accounted into the search process as well. the idea would be that instructables users could rack-up all their junk and save it as a list to their own digital library or, "inventory" of all the parts and tools they currently have and manufacturing processes they can do with said items. from there they could click "search by inventory" and include or exclude items from their total inventory to run a search based on that. for example i could select: -super old motherboard (or specific part number) -old motorcycle seat -some bolts (or specific sizes of bolts) search results would turn up projects based on the parts that i have selected, results would mention whether i am missing or have all of the tools or parts i searched for. imaginary examples might be stuff like: -strange computer motorcycle seat -cyborg motorcycle seat -a computer build from an old motorcycle seat -ride fast while computing fast -tune your old motorcycle with an old under-the-seat DIY ECU -etc. though, this sounds like a daunting task, especially with the numerous vague and sometimes seemingly useless projects people can come up with, instructables has already begun to specify categories and sub-categories (channels?) of project styles such as leather-work, CNC, electronics, wearables, etc. etc. and to add tags and specific names for parts, tools, and processes to a library would simply be a more detailed and concentrated addition to these categories. what i'm hoping we could maybe do is add an option to search by ingredients in a similar way to how myfridgefood.com searches for recipies (maybe we could start by adding a similar function to instructables' recipies category?). it's just an idea and i'm not sure how willing the developers of instructables are to allow this community to contribute to the redesign or addition of search options.  aside from searching by ingredients, it would be extra helpful to know if there are other instructable members in our local neighborhood who are willing to collectively use their junk to make a project together! combined inventories could lead to a world of possibilities for creations and networking! maybe one person doesn't have enough junk to make their own forge but a whole neighborhood would be willing to contribute their efforts to make a community forge? i know my dad isn't the only one in our neighborhood with a garage-full of junk, and i think with everyone's junk maybe we could send a project to the moon, or make a super awesome rat-rod, or make a community wind-turbine farm, and get all that legally approved by our local comminity! maybe as a neighborhood we could create something only large companies are currently capable of manufacturing!?!?!? and finally on a side note i think maybe there should be a filter between serious and non serious ("fun") projects. or at least a rating service so that readers can scale how serious they think a project is on a serious to fun scale with fun and serious being in the middle. that way everything stays positive and constructive; no negativity for being too serious or too fun! yeah that last idea is pretty crazy, but maybe we could start with my first small idea of searching by parts/ingredients? let me know your thoughts! thanks!!! (expecting answers along the lines of where to start, whether or not other instructable-type websites exist, i know for a fact this is possible and doable since myfridgefood.com basically has the format set up to do so.) i'm open to (negative) answers that completely tear apart my idea as long as they are educated and provide specific counter-reasons as to why it would not work. i'm fairly certain the first idea is possible, it's just a matter of convincing the developers to get on board and getting everyone to start labeling the parts, tools, and processes in their projects (they are already "tagged" maybe we could start there?)
