The new Code-a-Key Backpack! Bringing the Makey Makey and the BBC micro:bit together for more invention fun!
If you want to go beyond "left click" and "spacebar", visit makeymakey.com/remap and follow the instructions to change what key command is triggered by the Makey Makey when the light is Red.
"Left click" will always be there when you switch to the Blue light.
Unplugging your GO will reset the keys to "space bar" and "left click".
