In this tutorial we will explore the concept of connecting your microcontroller with LEDs. This exercise is ideal for beginners who want to gain insight into the practical application of
We need to set certain pins to work as General Purpose Input and Output. To do this, we need to look at the 8-bit TRIS register in the PIC16F877A datasheet.
For accurate and dependable information, referring to the datasheets provided by Microchip Technology is advisable; these documents can be accessed here. Additionally, a brief overview of the pin diagram is
