What is Relay?

Relay is a electromechanical switch that open and close circuits electromechanically or electronically. Relay have total five pins. Two pins are connected with a coil. One pin is called the common pin. It is connected with another pin which is called NC. The common pin is not connected to the other pin when relay is not working. The last pin is called normaly open (NO).

Blinking LED using PIC16F877A Microcontroller

LED blink using microcontroller is the first step for microcontroller programmer. It is quite easy for the students if he/she know the C programming. In this section you need to know the embeded C language for microcontroller programmin and also need the simulation software to test the .hex code. the simulation software neme is proteous professional that i used. Several tutorials will be found on youtube if you need to teach the operation and settings.

This was my first microcontroller project which have four LED blinkin secquentially.
