I first experimented using the IR led to transmit 2400 baud serial to the phototransistor. I programmed my <a href="http://www.arduino.cc/en/Main/ArduinoBoardDiecimila">Arduino Diecimila</a> with the sample serial program altering the baud rate and allowing it to run in a continuous loop. http://www.ohmpie.com/laserModem#comments Electronics Programming Mon, 11 Aug 2008 19:03:26 -0700 esalazar 23 at http://www.ohmpie.com http://www.ohmpie.com/laserModem Serial data transition from a Arduino controller using a standard red laser, photo transistor and an instrumentation amplifier. <br><br> This started when I ordered an <a href="http://www.sparkfun.com/commerce/product_info.php?products_id=241">IR led and phototransistor</a> pair from Spark Fun along with some spare ATMega168 microcontrollers.
