Building the Robot Vacuum Circuit: Part 1(L293D, Hobby Gearmotors, and Potentiometer) Remember to ground both sides you may achieve this with the battery's negative terminal and the Arduino's GND pin.Ģ.
As a result, the 9v battery will be linked to the left side of the breadboard, while the components will be attached to the Arduino's 5v pin on the right side. The Arduino's 5v will be used to power the remainder of the components. Since the Hobby Gearmotor requires more current than the Arduino's 5v(VCC) pin can deliver, we'll also be utilizing a 9v battery to power the two gear motors. I've also attached a schematic view of the circuit to help you further while your wiring it up! Use the TinkerCad image above to help you throughout this process.
