- Cables used a wire filament helix hit one square millimeter in size. You can get up to 14 amperes of current low loss wire resistance 1 ohm to 100 meters
- a dry cell battery, 12 volt 12 AH
- voltage converter circuit. Due to supply only Battery 12 volt, but the range of microcontrollers and ICs some pressure just five volts, it must have a circuit to convert the voltage from 12 volts to 5 volts using IC's. a voltage regulator
