Beginning Arduino Programming

Project 9: Serial to Servo

Sending information to the Arduino board to control how it functions is as useful and almost as easy as sending information from the Arduino board. For this project, we will look at the Servo project from the last chapter so that we can use the Serial functions to send data to the Arduino board to control the servo's position. For our sketch to work properly, we need to change the communication mode from No line ending to Newline in the drop-down menu at the bottom of the Serial Monitor.

Hooking It Up

Because the circuit should be familiar, we won't dwell on it too much. Figures 10-1 and 10-2 show the standard servo schematic and illustration that we used before with nothing else needed. The following source code, however, ...
