When an external switch or logic signal changes state, the Servo Trigger tells an attached servo motor to move from position A to In This Tutorial. This hookup guide starts with some background information about hobby servo motors.
We're not going to get too deep into the basics of hobby servos in this hookup guide. If you want more detailed information, check out our Hobby Servo Tutorial....
Tutorials trigger hookup guide -- tourBefore we power up, take a moment to double-check your work against the photo below click on the picture for a larger version. The servo trigger can be used with a wider variety of external components than used in the example above. If the current track is playing, it stops. The default mode implements toggling control. Within the Servo Trigger, each mode uses the same basic set of states, which in turn describe how it drives the servo.

- This allows the trigger inputs to be decoupled from specific tracks, so that a PC or microcontroller can monitor the trigger inputs and then start any track or sequence of tracks via the serial control port. No matter your vision, SparkFun's products and resources are designed to make the world of electronics more accessible.

- In particular, make sure that the power and servo connections are oriented correctly. Tap the switch again, and it will go back to the original direction.

The PCB has a chip on one side, possibly a small microcontroller. Resources and Going Further. Checking this option makes the trigger active high. You can select among these by changing the compile-time symbols in the project. However, to follow along with this tutorial you will need a few things besides just a WAV trigger board. If A is higher than B, then the servo will turn counterclockwise when the switch is actuated. If you continue to have problems, make sure that your microSD card is compatible.
