I need advice on the way to use Arduino to control the turn on/off switch on an ir.remote. I searched in the library of Arduino Forum but only found ref. to making Arduino into an ir emitting remote itself or using an "opto-isolator". I wish to use the original remote and just bypass its turn on/turn off switch. I already soldered 4 wires to the 4 feet of the switch. The remote operates on 2x1.5 V AAA batteries (3V). Can I just connect the Grounds together and connect the other lead to a digitalPin through a 2000 Ohm resistance ?
I've used a transistor in the past to act in parallel with an IR remote button.
Thank you! At first reading of your method I feel that it is way above my head. I was hoping for a somewhat more simple solution.
Is there an easier way or one that is more understandable for less experienced "Arduinus"?
