Description Attachments

The SparkFun Servo Trigger is an innovative robotics board that streamlines the operation of hobby RC servo motors. It offers a fuss-free way to control servo motors, without the need for any programming. When an external switch or logic signal changes state, the Servo Trigger instructs the attached servo motor to transition from position A to position B. The Servo Trigger comes with on-board potentiometers to adjust the start/stop positions and the transition time. All you need to do is connect a hobby servo and a switch.

The Servo Trigger is powered by an Atmel ATTiny84 microcontroller, which runs a small program to control the servo. The board features three potentiometers - 'A' for setting the position the servo holds when the switch is open, 'B' for determining the position the servo moves to when the switch is closed, and 'T' for setting the transition time between positions A and B. The Servo Trigger board is also energy-efficient, drawing just about 5 mA at 5V. However, be aware that the maximum supply voltage should not exceed 5.5 VDC. The design of the SparkFun Servo Trigger allows for easy daisy chaining of boards by simply connecting the VCC and GND pads on adjacent boards.

For more advanced usage tips, configurations, and modes, refer to the Hookup Guide in the Documents section. This product was originally inspired by our friend in the Oakland area, CTP. Do give him a high-five if you see him!
