How to use Arduino as a TV remote?

Other Hardware Sensors
1

Hi all Arduino lovers :smiley:

I have a 29PT8xxx CRT TV. I want to shut my TV down with my IR led. I haven't got a IR Sensor, so i don't know how to find my remote's signal code.

I only have a LDR and an IR LED. Can i decode my Remote's signal code (hex code) and send it to my TV using a LDR and IR LED?

I can't buy a IR Sensor now, so i must make it with only a LDR and an IR LED.

Note:

Board Model: UNO
Arduino Software: 1.6.5

Thanks :slight_smile:

You cannot use the LDR to read the IR code. You need a IR receiver (not just an IR phototransistor).

Do a search of the site for remote controls.

Edit.

An LDR is not responsive to IR and is relatively slow responding to light.

Google search for IR usage and code.
