Build Your Resume To Get Connected for Jobs and Internships - Resume Builder
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.
