This is a project used to control the speed of DC Motor using pulse width modulation. We use DC fans in many systems in our day to day life. For example, CPU fans, fume extinguishers and many more ...

We are ready to consider a practical example in which we will use the Arduino and L298N IC to control a DC motor. We will use the PWM signal from Arduino to control the motor speed, and we will change ...

Temperature and monitoring using Arduino The MCU on Arduino drive the motor driver to control fan speed. Fan Speed Control Technique: Pulse-Width Modulation (PWM): PWM regulates fan speed using a ...

Figure 1. Arduino Uno. available to control a DC motor .The Arduino Uno is one of the most common starter boards that are being used to control multiple kinds of motors, especially DC motors, because ...

Speed control. We can use an Arduino board to generate a pulse width modulation (PWM) signal that controls the motor's speed using the H-bridge circuit shown in the diagram. A PWM signal has a certain ...
