Building a discrete transistor DC motor driver circuit

You have built and tested a transistor LED flasher using discrete electronic components. You have used the M5Stack Core as a programmable controller, thus setting various LED flash rates. You will use the operational concepts implemented previously with the transistor LED driver project to build an M5Stack Core-operated DC motor controller. Figure 5.16 shows the concept of the M5Stack Core interfacing circuit.

Figure 5.16 – The concept of the M5Stack Core interfacing circuit

With the M5Stack Core interface illustrated in Figure 5.16, along with the electrical wiring diagram shown in Figure 5.17, you can wire a transistor DC motor driver circuit to an M5Stack Core. The unique feature of this transistor DC motor driver is its ability to operate an electric motor using this interface. The transistor DC motor driver wiring diagram is shown next.
