

Introduction

The Servo Trigger is a small board that helps you deploy hobby RC servo

motors. When an external switch or logic signal changes state, the Servo

Trigger tells an attached servo motor to move from position A to position B.

The Servo Trigger in action.

To use the Servo Trigger, you simply connect a hobby servo and a switch,

then use the onboard potentiometers to adjust the start/stop positions and

transition time. You can use a hobby servos in your projects without having

to do any programming!

In This Tutorial

This hookup guide starts with some background information about hobby

servo motors. From there, it jumps into getting the Servo Trigger working

with a small servo, then examines some of the inner workings. Finally, for

the adventurous, it explains how to customize the Servo Trigger by

reprogramming it.
