An RGB LED board, originally developed in fall 2014 by coredump hackerspace in Rapperswil, Switzerland for teaching kids (~10y) the basics of electronics.
The v1 consists of a potentiometer for each RGB color. The current is only controlled by the potentiometers. Therefore not too many LEDs can be driven at the same time.
In contrast to v2 the v1 is also missing a switch to turn on/off the power.
The v2 is more advanced and uses an Arduino Nano as controller. The arduino controls the RGB LEDs' brightness through PWM. The LEDs are switched with three MOSFETs. This enables the control of more LEDs at the same time.
