Hello readers, I hope you all are doing great. In our previous tutorial, we discussed the implementation of LED interfacing and blinking program with Raspberry Pi Pico using MicroPython programming language. So continuing with our previous tutorial, in this tutorial we will learn how to control the LED brightness using PWM (pulse width modulation technique).
As we mentioned above, in our previous tutorial we implemented the LED blinking program with a Raspberry Pi Pico board. Blinking an LED means turning ON and OFF and thus the process involves only two states that are ‘1’ (HIGH) and ‘0’ (LOW). But, sometimes it is required to change the digital output between these two (ON and OFF states) for example changing the LED brightness. PWM or Pulse Width Modulation technique is used to change ...
