Summary of PIC16F84 SIMPLE LED BLINK PIC-C
This article describes a simple LED blinking project using the PIC16F84A microcontroller. The circuit connects an LED to PORTB bit 0 (RB0) via a resistor, driven by a 4MHz crystal oscillator. The C code configures RB0 as an output and toggles the LED on and off every 250 milliseconds in an infinite loop.
