Making Simple Robots, 2nd Edition

To practice working with sensors, you can try an easy version that simply

moves the marker all the way left or all the way right. Then move on to the

version that moves the marker different amounts, depending on how far the

micro:bit is tilted. The program isn’t very long, but it involves a new concept

1. Begin by setting the servo in the neutral position:

• Open the Servos menu (see ...
