Microcontroller Based IR Remote Control Signal Decoder for Home Application
Nhivekar G.S. and Mudholkar R.R. Department of Electronics, Shivaji University, Kolhapur, Maharashtra State, India ______________________________________________________________________________ ABSTRACT The present paper describes a design and implementation of an infrared (IR) remote control signal decoder which can be used for various home control applications. For a demonstration we have designed remote controlled fan regulator and ON-OFF power supply switch. The entire system is based on microcontroller that makes the control system smarter and easy to modify for other applications. It enables the user to operate or control a fan regulator and operate the mains power switch from about 10 meters away. The control setting and output AC voltage of fan regulator has been observed. Key words: IR decoder, AVR, Microcontroller, AC dimmer. ______________________________________________________________________________ INTRODUCTION Today, electronics is used in home appliances for wide purposes including the motor regulation of a washing machine, the control of a vacuum cleaner, the light dimming of a lamp or the heating in a coffee machine etc. This pervasion increases rapidly because appliances require enhanced features, easy to built and modify as electronics based solutions become cheaper and more sophisticated. Within this evolution, the microcontrollers (MCU) progressively replace analog controllers and discrete solutions even in low cost applications. They are more flexible, often need less components and provide faster time to market. With an analog IC, the designer is limited to a fixed function frozen inside the device. Remote control facilitates variety of operation around the home or office from a distance such as fan regulators and mains power
