this Instructable I'll show how to control your stuff with your phone and the arduino board. I've controlled everything from smoke machines too christmas light's with this program.
sorry the video is kinda odd because my camera is trying to adjusting for the light difference.
Step 1: The parts
-Iphone/ Android(Using Iphone)
- The TouchOSC app (awesome app)
-Arduino 5v (any type)
-Breadboard (optional but recommended)
- A Mac or PC
-Some sort of remote or low power button (anything that runs on AA,AAA batteries is usually fine)
-If you want to control a appliance look at the last step fore more info.
and thats it!
Step 2: Open your device (low power)
Hopefully you can figure out this step by yourself. Remove a screw or two and open it. In the pictures Im opening an LED strobe lamp.
Step 3: Find the button
Now on the the circuit board from you device find the button/switch you want to control with your smartphone. For me it was the On/Off switch on the strobe lamp. if your opening a remote control you likely find these pads shown in the 2nd picture
Step 4: Solder to the contacts
Once you have found the contacts solder some wire to them, one for the positive and another for the ground. I strongly recommend using solid strand wire as its much easier to solder. For more help look at the photos.
Step 5: Connect the transistor
Now you will need to connect your transistor to your Arduino and to your device. Look at the picture below for how to wire it up. I have annotated it if you need help. That little black thing is your device. If you know the polarity of the wires you can connect the positive to the left terminal of the transmitter and the ground to the right terminal
If you want to control more buttons connect additional transistor's the same way but instead of using pin 12 use 8, 9 or 11
