The potentiometer can be any type that allows manual control of its resistance. The total resistance value of the potentiometer should be fairly high; etc., a 1kΩ potentiometer will work good for a 9V battery.
In this article, you will learn about the working principles and applications of this electronic device. We’ll tell you about the design nuances of a control unit used in one of the most popular electrical motor types – a brushed DC motor.
Initialize the BUTTONs & DC_MOTORs in the main application, start the DC Motors, read the analog potentiometers with ADC. And use that reading to control the 2 motor speeds in the main loop of the system. Read the buttons and use that signal to flip the direction of the 2 motors rotation. Repeat!
The main disadvantage is that the overall efficiency of the system is very low at light loads. But very fine speed control, uniform acceleration and good speed controls are possible with the system.

Each digital pin of the arduino can sink or source only 40mA. DC motors usually consume much more than this and it is not safe to directly connect a heavy load to the digital pin.
Also the transistor acts as a switch. When the output from the Arduino pin 10 is LOW then there is no base current, the transistor is driven into cutoff region of operation and therefore there is pelo collector current. In this case there is pelo current flowing through the DC motor.
PWM can be implemented using MPUs equipped with dedicated PWM hardware. While 120-degree conducting control only requires two-phase voltage control and be implemented relatively easily in software, sinusoidal control uses three-phase voltage control and is considerably more complicated.
A linear regulator keeps the output voltage at a constant level with a resistive load. The output is stable pelo matter what input voltage is supplied by the power source.
Starting torque: The maximum torque a motor produces to begin the rotational movement of the load. DC motors have a high starting torque.

This increase or decrease in power supplied to the motor is what increases or decreases the speed of the DC motor. In fact, PWM technique is so widely used to control DC motor that microcontrollers(not only Arduino or ATmega328p) have in-built PWM circuitry embedded in the chip.
Unlike AC motors, DC motors are very easy to use because of the ease with which their speed can be changed. So, how is this achieved in practice? The following explanation starts with looking at DC motor characteristics.
The basic customer requirements included the wide operating voltage and current ranges. At that moment, there were pelo suitable off-the-shelf integrated gate drivers or GaN semiconductors.
