Plug the main board, switch, buzzer and LED blocks into your baseboard like the picture. You can click on the picture to zoom in.
Plug in the cables like the picture - the switch block should be plugged into P8, the buzzer to P2, the red LED to P1 and the green to P0.
Plug in your micro:bit with the USB Cable, and transfer the program you have just downloaded.
Test it out! Can you work out what the program does? When the LED turns green you need to press the switch as fast as you can. The LED will give you green for a fast reaction, orange for medium and red for slow.
Can you change the program so that it sounds the buzzer when the game starts? Here's a hint: the buzzer is plugged into P2, and the block in the picture will turn it on.
For advanced inventors - can you change the program so that it sounds the buzzer for each 0.1 seconds it takes you to press the button, to tell you how well you did? For example, if it takes 0.4 seconds to press the button, the buzzer should beep 4 times.
