What You Should See

At the beginning of the program the servo should move to 90 degrees and then react to the orientation of the micro:bit. If you hold

the micro:bit flat, the servo will be at 90 degrees. Then if you tilt the servo to the left, it will move less than 90 degrees toward the

value of 15. If you move it to the right, the servo will move toward 165.

Troubleshooting

This Seems Backward

You may be holding the micro:bit in a different orientation. Flip it around and try again!

Servo Isn’t Working

Double-check your wiring! Remember, red to 3.3 volts, black to ground, and white to signal.

Experiment 11: Using the Compass

Introduction

This experiment is just plain fun! Have you ever used a compass? Are you a little confused in terms of which direction to go? Fear

not! We will build a digital compass that will keep you on track to the North Pole using the micro:bit’s onboard compass chip!

Parts Needed

You will need the following parts:

1x micro:bit

1x Micro B USB Cable

1x micro:bit Breakout (with Headers)

1x Breadboard

4x Jumper Wires

2x LEDs

2x 100Ω Resistors

Didn’t Get the SIK for micro:bit?
