This is a fundamental experiment for LEGO Power Functions wire. The LEGO Power Functions 8871 Extension Wire 50cm (4506077) has 3 different plug: LPF female, male plug and 9V Electric System male plug. According to the Power Functions pinout: 9V, GND, C1 and C2 pins will be explored, and test the wire connection and voltage measurement using Multimeter. Finally, make a Power Functions DIYExtension Wire with additional connectors, to show how the connectors work with LEGO DIYBattery Box and DIYMotor.

WARNING: Do not try to make this experiment unless you know exactly what you're doing! I will not be held responsible for any damages of your Power Functions parts or any other parts!
