Easily control your iPod using Arduino
Easily control your iPod with Arduino using serial commands. This instructable includes the schematic, the code and some extra info; everything you need to make this work.
USB,battery or wall power supply powered.
Step 1: What you need
5x 1K ohm resistors
2x 1M ohm resistors
1x 12K ohm resistors
1x 1.5K ohm resistors
4x normaly opened push buttons
3.5mm audio jack
Step 2: Schematic
In the protoboard.
Arduino serial is 5v while iPod logic level is 3.3v. Because of it we need to add a voltage divider.
The two 1M ohm resistors are required to make a 500k to select the device.
The dectect cable is conected to iPod TX pin and use to let the arduino know when an ipod is conected.
Step 3: Code info
Basic comunication protocol. Dont worry, everything is in the code file.
Step 4: Download the program
Here is the arduino code:
