Description
In this project, we are going to use a PIC microcontroller to remotely control few AC loads by just using an IR remote. At the end of this project you will be able to toggle (ON/OFF) any AC load using an ordinary Remote from the comfort of your Chair/Bed. To make this project more interesting we have also enabled a feature to control the speed of the fan with the help of Triac. All these can be done with simple clicks on your IR remote. You can use any of your TV/DVD/MP3 remote for this project. The different IR signals from the remote are received by the microcontroller which then controls the respective relays via a relay driver circuit. These relays are used to connect and disconnect the AC Loads (Lights/Fan).
[You can find the complete project with detailed instructions on circuit digest][1].
