Today, I created a reaction game for my micro:bit. You will need to do a bit of DIY to make your own, but it’s really easy! All you need is some foil, cardboard and four crocodile clips. If you look at this webpage, you can see how to set it up.
But instead of using the code shown there, I’ve got an improved version which you can find using the link below. Make sure that you go into the program and select how many rounds you want to play as well. The default number is 5.
I’ve also posted this on GitHub, so feel free to edit and improve it. If you want me to update the program send me a pull request or if you find a bug send me an issue on GitHub.
