Do you want to control your TV and several other gadgets that are IR controlled? Ya but my phone doesn't support it because it doesn't have an IR blaster.Don't worry here a gadget that gives IR control to any phone and the thing it needs is bluetooth!! YES!! bluetooth!! The gadget also increases the range of your control!! As it covers the distance range of bluetooth as well as infrared!! It was made in very less budget and requires some components including arduino uno and bluetooth module! Basically the phone sends signal to HC-05 (bluetooth module) and further bluetooth module sends the characters to arduino's serial port and arduino sends particular IR signal decoded from your remote!! It works with all TV remotes!!I etched the circuit on PCB to make it more efficient and useful!! Here 's a demo video of it but I'll publish full tutorial on making it soon..
You'll require to install IrLib master library that is attached below. Unzip it and then copy the files to libraries folder of arduino IDE. Either you can install it by directly opening IDE and under sketches install zipped libraries.
