William writes:Moving forward in the adventures of the electrical nature - it was already time to dive into the programming side of physical computing. Lab #2 consisted of wiring up a simple circuit with a switch and a couple of LEDs and being able to program a Arduino board to process simple logic through authored code. After working through the previous lab - I found the circuit-boarding side of this lab to be far easier, even with the addition of the Arduino microprocessor, which as the time was completely foreign to me. Below are a couple of pictures of the process, plus a link to the source code for my first Arduino program.[more]

The hardware is very simple, and is based around an Arduino board that is using a bit-banging SPI technique to write data to a 100KΩ digital pot (model MCP42100). Approximately 7 of the 8 bits of data actually change the value of the filter (this could be due to the resistance value of the pot).[more]

This is an infrared remote control receiver for Arduino.It woks fine with any RC5 format remote control.The received RC5 code will be send to the serial port to be read on the serial console hyperterminal on windows at 9600 Baud-8-N-1.[more]

This is an Arduino-based oscilloscope.With this instruction int val_read = ((analogRead(0)*5) / 1024.0) you can see the signal as you want.The display of this oscilloscope is a color graphic LCD 240×320.(All documents in Spanish)[more]

This is a tutorial how to control an iPod with Arduino and remote to getting some music and sound.They use an unofficial remote control that found on the worldwide auction site for around 10 USD. TIL116 opto-isolator used between the Arduino and the remote to safely send signals in between the two. The remote works by you pushing a button which closes a circuit and that is interpreted in a certain way by the iPod.[more]
