Building an Arduino infrared recorder and remote
With Arduino and some basic electronic components, we can easily build an infrared recorder and remote control. This allows you to record any infrared command (code) sent by an infrared remote control. Also, it allows you to resend the recorded infrared command to a target device and the device will treat the command the same as the remote control's command. Therefore, you can playback any recorded infrared command and control your respective infrared device.
The typical uses of applications are:
Switching on/off your air conditioner
Adjusting the temperature of your air conditioner before you arrive home
Anything you control with the traditional remote control
The following hardware and software components are needed to build a basic IR remote.
Hardware
The Arduino Uno: R3 board
The Arduino Ethernet Shield or Arduino Ethernet board
An LED light: Infrared 950 nm
An IR receiver diode: TSOP38238
A 330 Ohm 1/6 Watt resistor
A mini pushbutton switch
