Here is a typical usage application for this driver code in order to initialize & start a DC Motor, read an analog potentiometer with ADC. And use that reading to control the motor speed in the main loop of the system.

So, in my opinion, a MOSFET with a maximum drain current greater than 5A and a maximum drain-source voltage of 36V should work fine for a long time.

Connect the resistor to one terminal of the DC motor. Attach the wire to the unconnected side of the resistor. This is best done using a wire instead of directly so that the resistor(s) are out of the way of the motor application.

Generated because of the constant switching of the commutator, it affects neighboring electronic components. To reduce it, you could implement different filters that protect the wires from EMI.

A breadboard, electrical tape or solder to make solid connections in the circuit. A tutorial for using breadboards can be found below.

The example LABs will put everything under test and you’ll see how and when to use each of these functions.

We’ll have to do this step just to have the TIM_HAL files added to our project by CubeMX. And also it gives us a startup configuration for the PWM channel of that specific timer module as we’ll see hereafter. This is the best way to keep the code generic and portable to any STM32 microcontroller.

 In the above wave forms you can see that the frequency is same but ON time and OFF time are different.Two applications of PWM control using arduino is shown here. Controlling the LED brightness using arduino and motor speed control using arduino.

Three or more wires are needed. Insulated wires work best as they prevent wires from crossing and the battery from short circuiting.

To complete this project, you will built on the circuit from Project 2. If you have completed Project 2, you will only need one additional component: the HCSR04 ultrasonic distance sensor. This sensor will replace the potentiometer.

A 10k Ohm potentiometer is used here. The ends of the resistive track are connected to 5V and ground, respectively, and the wiper pin is connected to the A0 analog input pin of the Arduino UNO.

As the wiper moves from one side to the other, it generates a different voltage within the range of 0 to 5V, which is fed to the 10-bit ADC of the Arduino UNO.

I would like to have a little give though with the transistor, so that if I later get a fan with a slightly higher wattage, it wont burn out the system; hence want to switch from the 800mA limit on the 2n2222a.

It can supply up to 1A of current and voltages from 4.5V to 36V. This means the L293D motor driver is ideal for building multi-wheel robot platforms. Here’s a diagram of the L293D showing how to connect the motors:
