Wiring Diagram:
Connect crocodile clip leads between the Pin 0 output on the Klip Motor board and P0 on the
ACCESS:bit, the Pin 1 output on the Klip Motor board and P1 on the ACCESS:bit, the 3V output on the
Klip Motor board and the 3V connection on the ACCESS:bit, and finally the GND connection on the
Klip Motor board and the GND connection on the ACCESS:bit.
The ACCESS:bit requires its own battery supply in order for the servo to be driven (3 x AAA).
Program a BBC micro:bit (explained in the ‘How to code it’ section of this guide) and the slot this into
the edge connector on the Klip Motor board with the LED display facing up (as shown in the wiring
diagram above).
A short test program can be found using the link below:

This program moves the barrier up, and beeps twice when button A on the micro:bit is pressed, and
moves it down, with a single beep when button B is pressed.
