If you have the the new micro:bit, you can use the gold logo as another input in your projects. It’s like having an extra button.

The touch logo uses capacitive touch, sensing tiny changes in electrical fields to know when your finger is pressing it – just like your phone or tablet screen.

You can trigger events in your programs when you press it like a button, but also when you first touch it, when you let go and if you press it for longer.
