In this video, I show the instructions manual (2 pages actually) and explain what this little regulated power supply kit does.
It's more than a regulated power supply since it's also a square wave generator (RC oscillator), a logic pen with either LED or buzzer output.
Watch out as mine didn't have all the connections for the buzzer circuit. Easy fix though.
