IR Sensor interfacing with microcontroller (Mikro C)

Welcome To MINA TECHNOLOGY.

In this tutorial we will learn how to interface IR Sensor with Microcontroller. Here I am use PIC16F877A Microcontroller and LM16x2 Lcd display. You can watch the video or read the written tutorial below.

IR SENSOR

The IR sensor consist IR signal transmitter and IR signal reciver. The IR signal transmitter emit infrared light. The infrared light is not visible of human eye.
The IR signal reciver is recived the infrared light. When the obstacles or surfaces come in front the IR sensor then the infrared light is reflection. The IR signal reciver is recived this infrared light reflection.

     while(1){

                        }

                        }
              }
