What is the reset pin of PIC 16f877a?
PIN 1: MCLR: The first pin is the master clear pin of this IC. It resets the microcontroller and is active low, meaning that it should constantly be given a voltage of 5V and if 0 V are given then the controller is reset.
What is PIC IC?
PIC microcontrollers ( Programmable Interface Controllers), are electronic circuits that can be programmed to carry out a vast range of tasks. They can be programmed to be timers or to control a production line and much more. This is used to connect the computer to the microcontroller circuit.
