AVR Tiny based simple switch for any rc receiver. Allows to turn off / on lights, sound effect, retracts chassis, using free servo channel.
Following project contains AVR Studio solution, pcb and schema files (Eagle) for remote controlled swich. I'm using that switch for enable / disable LED light on wings of my flying model. This project is closed . There is no future development plans.
To make it work you need, AVR Tiny 25 uC, two transistors, some AVR programmer and AVR Studio 5 or higher.
RC Switch can be plugged into any receiver servo channel. It recognizes minimum and maximum position of radio stick.
