Understanding the Microcontroller GPIO – GPIO Working Explained

Understanding the Microcontroller GPIO

In general, whenever we learn a new programming language we used to write the “Hello World” program first. Likewise in the microcontroller, we try the LED Blinking program. To blink the LED, we need to access the  GPIO. If you are a programmer, you can just write “1” to the GPIO pin to make it … Read more
