Hardware of the RC car

Preview

Components

• Arduino board: Brain of this project

• Foam core: material for car body

• Motor driver: Electrical device that acts as a bridge between a low-power microcontroller and a high-power motor

• Motor * 4
• Plastic wheel * 4

• Bluetooth module HC-06

• 9V battery * 2: One is power for arduino, and another is power for motor driver.
• Battery case
• Bolts and nuts
• Jump wires

• Lead wires

• Male crimp pins

• Jumper wire housings

Conclusion

One limitation is that the car slows down significantly while turning. However, it is still unclear whether this is caused by the wheel design, the materials used, or the motor’s limited torque.
