Animatronics Made Easy with the SparkFun Servo Trigger

The SparkFun Servo Trigger is perfect for those applications where you’d like a hobby servo to move from one position to another — at exactly the same speed each time — but you don’t want to program the behavior. Instead of controlling the movement with code, you simply adjust three potentiometers: one for the start position, one for the stop position, and a third for the time you want it to take to move between positions.

The board uses an Atmel ATTiny84 microcontroller and can be easily chained by connecting the VCC and GND pads on adjacent boards together on adjacent boards. Just be sure not to run more that 5.5 VDC to the board.
