This simple system can be used with the AtmoWin software, or using the AtmoLight plugin in VLC (media player) , it connects to your PC using the standard USB connection on your arduino.
It has only one channel, but it still provides a nice effect.
A video of it in action:
This could be expanded to two channels, for more info see the last step.
Step 1: Parts
- An arduino
- 3x 2k2 resistors
- 3x an NPN transistor, capable of switching 12Volts (I will be using a 2SD1062)
- A 12Volt adapter (wall wart)
- A barrel jack
- A 12Volt RGB (common anode) LED Strip (I will be using this one)
- Header pins
- Some prototyping board (I will be using some perfboard)
