Universal IR Remote Control using Arduino and Android App
I started this project in order to get rid of various remotes at my home and build something single which could incorporate features of all of them. I got this idea when I saw one of my friend’s mobile phone with built in IR blaster, at that time I decided not to buy a similar phone rather make my own device which should be compatible with my existing handset. So here we are going to Convert an Android Phone into an IR Remote using Arduino to control various devices at home.
- Arduino Uno
- IR LED
- TSOP-IR receiver (1838T)
- Bluetooth module (HC05)
- Android Device (Phone, Tablet, etc.)
Generally we use two remotes to operate TV at home, one for television and one for Set-Top Box so here in this Project I am targeting these two remotes and making an Android Phone working as IR Blaster so that TV can be controlled with the Phone, without touching any of the Remotes.
Using an Arduino Uno board just made it easier for me to deal with the IR decoding and encoding part. The custom made shield just adds on to the convenience part of this project. The shield consists of a TSOP IR receiver (1838T), an IR LED and a Bluetooth module (HC-05),
You can either build the custom shield or can directly connect the components to the Arduino as shown in the ‘Circuit Diagram’ in below section.
