turn on my projector with an Arduino

Hello,

For a school project, my teacher challenged me to find a system to remotely turn on and off the classroom projector (acer-bs312), without using the buttons on the device or the remote control (which is broken).

While doing some research on the internet, I found some systems to do this manipulation and I came across an old topic on this forum. I think that using an Arduino is the easiest method.

Would you have any documentation to advise me on how to make this exercise a success? I am a beginner: for the moment, I have only done exercises on light sequential control and others.

Thank you in advance for your help :slight_smile:

A common method is to use an IR sensor to read what the remote transmits when you press the 'on' button and then use an IR LED attached the the Arduino to emit the same pattern.

Since your remote is broken, part one will be tricky but you may be able to look up the details of your particular projector on line and find out what the signal is.

The project description looks somewhat, err, special. How exactly are you supposed to turn on the projector, by a mains switch or by a remote switch in parallel to the mechanical buttons, or by hacking the remote control receiver inside the projector? Have you (or your teacher) ever researched this part of the project?

It’s not advisable to just cut the power to a projector virtually all projectors run the fan for several minutes after you turn it off, best would be to send the i r code

Methinks getting a replacement remote control is even easier.

OR even borrow one from the classroom next door.

It sounds like the device is already operable, albeit without the luxury of a remote.

I think it's a learning exercise for the OP, rather than a real need to get remote functionality again.

I know, that's very well possible, but not part of the posted specifications.

Having access to a working RC can be a great help to getting this to work (and the RC can be used while the student figures out an alternative solution).

Here I was thinking using hot glue and a servo to have the Arduino actually press on the existing power switch.

Then is becomes a matter of how are you going to tell the Arduino to turn the projector on and off.
