PIC16F877A – Relay Interfacing

Relay interfacing with LPC2148

This article is a continuation of the series of tutorials on the PIC16F877A Microcontroller. The aim of this series is to provide easy and practical examples that anyone can understand. In the previous tutorial, we have interfaced the DC motor with PIC16F877A. In this tutorial, we will learn Relay interfacing with PIC16F877A. Relay is a very important component … Read more

8051 – Relay Interfacing by using ULN2803

Relay interfacing with LPC2148

In our previous delay, we have seen DC motor interfacing with 8051. In this tutorial, we will learn Relay interfacing with 8051. Relay is a very important component to interface the heavy appliances with the help of a microcontroller. Relay Relays are devices that allow low power circuits to switch a relatively high Current/Voltage ON/OFF. A relay … Read more
