Part 14: Infrared
This is lesson 1 of 5 lessons. In this lesson we learn how to capture and decode infrared code from Infrared Remote Controller. Either Black Remote
, white remote or your TV remote.
We need the IRremote library to be installed first. Full details is shown in the video. We will use VS1838B IR or infrared receiver. The receiver
is sold just a bare part of installed on PCB. This tutorial will show you to use both.
This IR remote series has 4 codes
- How to decode IR remote code and Arduino (this code)
- How to turn ON/OFF an AC bulb using any remote control and Arduino/li>
- How to control a TV using Arduino as remote control
- How to control a DC motor using Infrared remote and Arduino
- How to control a servo motor using Infrared remote control and Arduino
/*
* Original code and library from - http://arcfn.com
*
* Lesson 101:
* This code decodes for keys of Black IR remote and White IR remote
* sold on eBay for Arduino.
* You have to select the type of your remote as Black or White in the code bellow
* and also select your receiver 1838 either as PCB or bare module. See video for details
