What does PWM mean in Arduino

What is PWM in Arduino?

We will learn what PWM is means in Arduino in this lecture.

PWM stands for Pulse Width Modulation. Using a digital signal that pretends to be analog is called PWM.

Remember, the resulting output will always digital, even when it is PWM. See video for how to define PWM in coding, which pins are for analog output, etc. Learn, duty cycle with a graph and how you can generate delay in a microsecond.

You can use PWM in creating an application like a dimmer, speed-controlled motors, etc.

In the next lecture, we will learn about serial communication.


  • PWM stands for Pulse Width Modulation, which is a technique used to control the output frequency of an electrical device.
  • The Arduino PWM Tutorial will walk you through how to set up a basic circuit and use the PWM function on your Arduino Uno to change the frequency of an LED.

  • PWM stands for Power-Wattage-Minutes, which is the power usage per hour. The higher the number, the more efficient your electricity bill will be.
  • PWMP stands for Power-Wattage-Milliamp per minute, which is the power usage per minute. The higher the number, the more efficient your electricity bill will be.

PWM is one of the most important things in electronics and Arduino programming. It is used for controlling the speed of motors, lights, and other devices that require speed regulation.

  • Analog PWM signals are the ones that vary continuously between a low state and a high state. Digital PWM signals are those that have discrete values between low and high states.
  • Digital PWM signals can be used for precise control of motors or other devices. Analog PWM signals are often used for controlling lights, fans, or other devices with analog output.

  • The PWM signal is an analog voltage that can be used to control the speed of a DC motor. It is used in many different applications such as robotics, home automation, and even cars.
  • In this article, we will learn how to use a PWM signal in Arduino. We will also learn how to make the LED blink using a PWM signal.
