Building the model car - hardware components

In this section, we will build a model car from scratch, but first, we will list the hardware required.

The following is a list of hardware components, with their required quantities, which are needed to build the model car:

• Wheels (4)

• L293D motor driver (1)

• 65 Revolutions per minute (RPM) DC Right Angled motors (2)

• Chassis (1)

• Photon (1)

• Li-Po battery (1)

• 3-6V DC power supply (1)

• Jumper wires (a few)

• Breadboard (1)

The following is a brief description of some of these components:

Wheels

These could be any model car wheels suitable for use with DC motors. The ones we used for our project look like the ones shown in the following image:

L293D motor driver

L293D is an Integrated Circuit (IC) which is used to drive direct current (DC) motors. It is capable of driving the motors in either direction. It is a 16-pin IC, as shown in the following image:

This motor driver can simultaneously and independently control...
