On a 3 button mouse...

Is it possible to replace the IR receivers from the xy axis's, with a rotary encoder from the scroll wheel? Is it just a matter of removing the IR receivers and putting in scroll encoder dials from other mouses? Now on top of that same idea, can you use pots instead of the rotary scrollers? I cannot find a pinout from a scroll wheel or a IR receiver anywhere...one of these would be nice also. The mice I'm speaking of are the early type non lit underneath. However a workup of both types wouldn't hurt as this will help with the newer stuff. End result being able to use 3 separate dial axis and buttons from one HID mouse board.?

Arduino Script Issue?

Hey world, I am making device that will automatically water my xmas tree: I am using the basic "button" script from the Arduino IDE examples. the only change I have made so far is instead of using an actual push button I am sticking 2 bare copper wires(the ground has a 10k resistor) into a jar.  When water is added to the jar the connection is made and the LED goes on. The problem is that it only stays on for like 7 seconds. I need it so as long as there is water in the cup the light stays on. any ideas? Below is a copy of the script. Thanks! const int buttonPin = 2;     // the number of the pushbutton pin const int ledPin =  13;      // the number of the LED pin // variables will change: int buttonState = 0;         // variable for reading the pushbutton status void setup() {   // initialize the LED pin as an output:   pinMode(ledPin, OUTPUT);   // initialize the pushbutton pin as an input:   pinMode(buttonPin, INPUT); } void loop() {   // read the state of the pushbutton value:   buttonState = digitalRead(buttonPin);   // check if the pushbutton is pressed. If it is, the buttonState is HIGH:   if (buttonState == HIGH) {     // turn LED on:     digitalWrite(ledPin, HIGH);   } else {     // turn LED off:     digitalWrite(ledPin, LOW);

Toggable MP3 player to play/pause with a electrical input? Answered

I know the title does a poor job of explaining my situation. Basically, what I want to do is make a simple one song MP3 player that will play when it has power, and not when it doesn't. But verses most MP3 players, I would want this to pause when it does not get power, not stop and then restart. I know I need a power source to the MP3 player to keep it's spot in the song when it's paused, but it's critical it has a play/pause function that is dealt with through a power source going to/through it.

I also need a lot of them cheap. I'm kind of crossing my fingers as to this actually existing....

Wireless button to talk to computer

Hello, I'm running some sessions with a multi-abled theatre group of kids and we want to create a piece of interactive dance. Each kids will carry a couple of buttons and when they press them they send a signal wirelessly to a computer nearby which is running the dance program connected to a projector so the kids can see what they are doing. So pressing their button could change the colour of the kids projection from red to blue.  I think I need to use a microcontroller inside a button but am not sure which one - cheap and small - bluetooth or wifi? How do I get the button press program onto the microcontroller? Finally how does the computer hear the signal? The dance program is written in Processing.  Is there a project that is similar?

Simple Audio to Button interface?

Dear Highly esteemed members of Instructables, I've had this Idea in my head, and I REALLY want to make it possible. I have a feeling that doing so would be a cinch if I had any sort of understanding of wiring at all. Basically, this is my idea. I want to use old buttons (and possibly an analog stick) from a gamecube or n64 controller and wire them so that they play a note when pressed. I don't necessarily need to include the analog stick in my design, if doing so would make the project a good deal harder. I'm looking to include about five buttons. And if the analog stick was included , at best I would want it to move the note in half steps, up or down, but I could also settle for setting it to it's own four notes, or not using it at all. As aforementioned, I have no Idea how any of this stuff works, or if it is even possible. So do let me know if this is even something that someone like me can do. And if it is, try to err on the side of over explaining if you can help it.

Change a switch into two buttons?

Hi, I'm trying to do the NES controller/mp3 player hack, and I bought a player small enough that the guts all fit into the available space in the controller case. However, it came with an on/off slide switch, and I'm trying to figure out if it's possible to modify that to the START and SELECT buttons instead. Thanks!

Circuit that emulate a push button

Hello Everyone! I'd like to ask your help in making this circuit. I want to make a simple circuit that emulates a push button switch: When powered on, the circuit will trigger a switch. When powered off, it will trigger the switch again. I'm thinking of using this for my home made coin operated PC. There are various options for the coin operated PCs from shutting off the monitor or keyboard & mouse to software triggered. But I'm thinking of using the stand-by or sleep option of the motherboard. My current setup is a coin slot that is connected to a timer circuit. When coin is inserted the timer is activated and a relay will turn on. I want to put the circuit to this relay output and connected to the pwr button of the PC. Hoping for your assistance,
