19 IR Remote Controlled Home Automation using PIC Microcontroller IR Remote Controlled Home Automation using PIC Microcontroller ELECTRONICS By Saddam   May 11, 2017 29 IR Remote Controlled Home Automation using PIC Microcontroller In this project, we are going to use a PIC microcontroller to remotely control few AC loads by just using an IR remote. A similar project  IR remote controlled Home automation  has already been done with Arduino also, but here we designed it on PCB using  EasyEDA ’s online PCB designer and simulator, and used their PCB designing services to order the PCB boards as shown in the subsequent section of the article.  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...
