Looking to do more with your BBC micro:bit? Unlock its potential with this Joystick breakout board for the BBC micro:bit!
Keyestudio joystick breakout board for micro:bit comes with AMS1117 chip. You can connect the external DC4.75-12V to power for micro:bit development board.
It can be used to simulate the mouse or keyboard. Connect the on-board pins 3V、G、P0、P1 to micro:bit main board to get analog serial port, connecting the Bluetooth devices.
This breakout board also consists of 6 buttons and a joystick. Connect the button and joystick to micro:bit pins.
Connect SELECT button to P7; MODE button to P6; UP button to P10; LEFT button to P11; RIGHT button to P9; DOWN button to P8.
Connect joystick X axis to P4; Y axis to P3; Z axis to P5. You can control the external devices by reading the interface states.

Note: we adopt V1.5 micro:bit in the whole tutorial, but our tutorial is also compatible with the latest version micro:bit. When doing experiment with latest micro:bit, you need to transfer code into Makecode online editor first, save code again then download it to micro:bit.

Wiring Diagram

Test Program

You can write the code below on micro:bit MakeCode editor: https://makecode.microbit.org/#editor
Downloaded the code you wrote well, send it to your micro:bit main board.

Test Result

Insert the micro:bit development board into keyestudio joystick breakout board, powering up, 2 LEDs will display as below:

• 1)Do not operate both joystick and buttons, 2 LEDs are off.
  
• 2)Press down any buttons ( including joystick Z axis button), red LED is on; release the button, LED will be off.
  
• 3)Turn Joystick upward, red LED on; joystick downward, yellow LED on; joystick leftward, yellow LED on; joystick rightward, red LED on.
  

Shield Experiment

In the experiment, we can insert a micro:bit control board on the shield, upload the corresponding test code, and set it as the Bluetooth host. We take a micro:bit control board, connect to the external device, upload the corresponding test code, set it as a Bluetooth slave. When both micro:bit control boards are powered up, the Bluetooth of two micro:bit control boards connect to the communication. We can control the external devices (such as LED buzzers, etc.) connected to the Bluetooth slave via external devices connected to the Bluetooth host (buttons on shield, joystick).
Here, we use this shield connected to a micro:bit control board to control the movement of a micro:bit smart car (KS0426). When using it, we only use the UP, DOWN, LEFT, RIGHT and SELECT buttons on the shield to control the smart car forward moving, backward moving, left turning, right turning and stopping. The dot matrix of the control board on the smart car displays the current motion status pattern.
