PIC Microcontroller Video Tutorial Series

PIC is a family of modified Harvard architecture microcontrollers made by Microchip Technology, derived from the PIC1650[1][2][3] originally developed by General Instrument‘s Microelectronics Division. The name PIC initially referred to “Peripheral Interface Controller“.[4][5] PICs are popular with both industrial developers and hobbyists alike due to their low cost, wide availability, large user base, extensive collection of application notes, availability of low cost […]

Turning on a LED using PIC16F84

This experiment turns on a LED when button A is pressed. The button is connected to the lowest bit of Port A (bit0). When the button is pressed, the line goes HIGH. This is called positive logic. The LED is connected to the lowest bit of Port B (Bit0). Any bit of any port can be
