Using Arduino UNO for triggering an IR Remote Control

[engineers_playground]

Hi there,

I'd like to trigger an IR remote control for a camera as shown below with an Arduino UNO.
That means the two contacts of the button on the remote control for triggering the camera must be short-circuited by the Arduino.

I'm wondering if this is possible only by connecting the contacts of the button to a selected port on the Arduino board and to ground.

What is the smartest solution for this task?

Thank you in advance.

That means the two contacts of the button on the remote control for triggering the camera must be short-circuited by the Arduino.

What is the voltage of the logic in the remote?
Using an opto coupler like the 815, 817 or similar is a safe way.

Why not get an IR transmitter, connect it to your Uno and have it duplicate whatever your camera button is emitting. The IR library can do that.

I'd go down the route suggested by blh64.

You need a an IR receiver connected to your Arduino to initially 'learn' what signals your remote control sends.
After that you can send the codes directly from your Arduino.

This way you are not limited to pressing a single key.

There is a tutorial about it at https://learn.adafruit.com/using-an-infrared-library

Hi.

Thank you for your ideas and solutions.

I didn't know anything about the IR library.

I'll have a detailed look at it.

Thank you.
