Become a human circuit.
Hold the GND pin (bottom right corner of your Micro:bit) and Pin 0 (bottom left). Program something to happen when you do this. You will have connected the circuit using yourself!
This example will spell out ‘I am a circuit’ using the LEDs on your Micro:bit when you connect the circuit.
Here are some starting points with ideas about how you can use the Micro:bit inputs and outputs in your game:
Use the accelerometer to control the movement of your
main character.
When the B button is pressed, the character will jump.
Shoot ammo when A is pressed.
Shake to switch to first person view.
A message scrolls along the screen of the Micro:bit when
you bump the castle.
