One is the transmitter circuit and the other is the receiver circuit the transmitter circuit will be connected to the 35mm audio jack for audio input and the receiver circuit will be connect to a speaker to play the songs. It uses an antenna to capture radio waves, processes those waves to extract only those waves that are vibrating at the desired frequency, extracts the audio signals that were added to those waves, amplifies the audio signals, and finally plays them on a speaker. The software consists of a Micro C language programmable microcontroller. This project is successfully improved the transmission distance and signal coverage area effectively with low cost of hardware, high communication speed and almost no limit to bandwidth. The Timer The main idea to understand is the timer is in a-stable configuration.

Both circuit based on the same microcontroller type which is PIC12F To see how the NEC protocol works read the following topic which shows how to decode this communication protocol using PIC12F microcontroller. In the circuit there 5 push buttons and each button sends a different IR signal code. PIC12F internal pull-ups are enabled by the software and the internal oscillator is used as usual. Each LED is remotely controlled from one button in the transmitter circuit.

IR Remote control transmitter and receiver using PIC12F1822 microcontroller

IR Transmitter and IR Receiver are commonly used to control electronic devices wirelessly, mainly through a remote. Here in our circuit we are building IR remote and its receiver. We cannot see Infrared light through our eyes, they are invisible to human eyes. The wavelength of Infrared nm — 1mm is just beyond the normal visible light. Everything which produce heat, emits infrared like our human body.

Looking for a way to tell how far you are in your garage? Tired of tying tennis balls to your ceiling only to have your dog get excited and pull them down? Looking to get rid of your boring old reflector? Have at least a basic idea on how circuits work and want to try something different? If you answered yes to these questions, then this instructable is perfect for you. In it you will be able to do build and use your infrared transmitter and receiver just by using a small list of parts and some time to build it! At the end of this project you will be able to detect your car as it approaches the wall inside your garage; the project will then tell you when to stop by turning on an LED thus letting you know when your car is safely inside your garage.

For the basic operation of the infrared transmitter, an electroluminescent IR LED is a product which requires care in use. IR LEDs are fabricated from narrow band​.

Infrared IR communication is a very common wireless communication technology. IR communication is an easy to use and inexpensive wireless communication. Some embedded projects also consists of IR Transmitter and Receiver Modules where they can be used as proximity sensors or distance measurement sensors.

    In the image, the IR Transmitter emits Infrared light modulated at a particular frequency. The IR Receiver will receive this.
