Hobby Servo Tutorial
With the Servo Trigger
Having programmed a servo example from scratch in the last section, there's another way to deploy servos that doesn't require any programming.
The SparkFun Servo Trigger is a small board dedicated to driving hobby servos. It has trimpots that allow you to set the servo positions and jump between the positions by actuating a switch. It is available in standard and continuous rotation versions. For more detailed information about the Servo Triggers, consult their respective hookup guides.
