Schematic

Wiring

Script – Vertical and Horizontal Voltages

Tests

Use the previous program at the beginning of this section to measure the sensor’s voltage output.  

After loading the script into the micro:bit, click Show serial in the micro:bit Python Editor.  There, you will see the voltage measurements updated every second.

Script – Joystick Matrix Pixel Control

Tests

Verify that the “pixel” on the micro:bit module’s 5×5 LED matrix display lights up and indicates the position of the joystick.
