Controlling a HDMI Switcher from an Aduino

Hi folks,

I've come up with an interesting project that I don't really have a clue where to start with.

I picked up a cheap HDMI switcher from amazon about a year ago (google HRS1051 and you'll find it) and it came with an IR receiver which plugs into the switcher via a 3.5mm head phone jack. The provided controller sends an in-fared packet to the receiver, which then sends a signal to the switcher - changing the input source.

What I'd like to try and do it simulate the a press on the controller from an arduino. This would be done by simulating the IR receiver over a male-male 3.5mm jack cable from the arduino to the switcher. I'll need to reverse engineer the communications protocol between the IR receiver and the switcher. And that is were I get stuck, not really sure how to approach this.

I don't really know how to go about that which is why I'm here, asking for advice. I believe I might need a "logic analyser" which is a tool I don't currently own but I can pick up a cheap one if needs be.

Thanks :)

Hi, Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.,148850.0.html

Look at these links.

You will see you can configure the Arduino to read your IR remote so you can then make the Arduino into a remote.
