The Combination of Laser Modem with an Arduino Microcontroller

Can you ever imagine that what is the combination of laser modem and Arduino microcontroller looks like? Well, you might think that it will be a hard task and requires many complicated steps to get these two different components assembled, but it is easier than you’re thinking of… Let’s cut the long story short and get this project started right away… You’ll need to apply the serial data transition from an Arduino controller using a standard red laser, photo transistor and an instrumentation amplifier. Before that, please do make sure that you’ve ordered an IR LED and phototransistor pair from the local electronic store with some spare ATMega168 microcontrollers. After that, is time to start the first experiment by simply using the IR LED to transmit 2400 baud serial to the phototransistor. Therefore, you have to program the Arduino Diecimilia with the sample serial program, which it’s altering the baud rate and will allow it to run in a continuous loop! This is surely an interesting and challenging project, hope you all will enjoy it and having fun with it! Continue reading
