These are the resources needed to make an official SpeedTest 3000 game.
First the components:
The pushbutton complete in blue
The pushbutton complete in red
Those come complete, with switch, socket, and coloured led.
Those are active buzzers, so when applied voltage a frequency is produced, no need to oscillate it.
Be careful, this nano has the CH340g USB to serial interface, read the description and update the drivers!!
You’ll also need regular geek supplies like wire, solder, hot glue, scissors…
The source code for the nano: SECONDREFLEX
If you need something else, or have questions, leave them in the youtube video comments so anyone can take advantage.
Cheers and good luck!!
