Infrared controls a LED Stripe

I like the recycling of electronic components that have already been retired and so today a remote control from an old HDMI switch is used and an infrared receiver that is still in its cable.

With this we will switch a 5V DC relay to which a separate 12V DC circuit is connected to switch a green LED strip on and off.

This article is intended to encourage you to go aside and not buy everything new.

Unfortunately I can no longer find the sketch. I'm sorry.

The challenges:

• Determination of the control codes of the remote control of buttons 2 (on) and 3 (off)

HDMI Switch - 3 Port Amplifier Selector - Remote Control

Key 1: "1373912347" + "4294967295"

Key 2: "2351064443" + "4294967295"

Key 3: "713627999" + "4294967295"

• For the assignment of the PINs, refer to the data sheet of an infrared receiver

• The connection of the trigger from Arduino A10 to the relay
