Relay Interfacing with PIC Microcontroller

In this project we will interface a Relay with PIC Microcontroller PIC16F877A. Relay is a mechanical device to control high voltage, high current appliances ‘ON’ or ‘OFF’ from lower voltage levels. Relay provides isolation between two voltage levels and it is generally use to control AC appliances. From mechanical to Solid state relays, there are various type of relays are available in electronics. In this ...

Interfacing 74HC595 Serial Shift Register with PIC Microcontroller

There are possibilities in embedded design where you do not have enough I/O pins available in your microcontroller. That can be due to any reason, may be your application needs multiple LEDs or you want to use multiple 7-segment displays, but you don’t have required I/O pins in your microcontroller. Here comes a perfect component, shift register. Shift register accepts serial data and give parallel output. ...
