If you've seen my other instructables, you know that our son has muscular dystrophy. This is one piece of a project to make things more accessible for him.
We have a door that is operated by a garage door opener remote. This has been fantastic in letting John come and go on his own. But, the button on the remote is a little bit difficult to push, and the remote is constantly in the way or falling off the wheelchair.
So, this project is to have the remote voice activated instead.
I opened up the remote to see how it worked, and found that it uses a simple button to connect a circuit and send its signal.
If I touched a wire to two legs of the button, it connected the circuit and made the door open. So, my plan was to solder a wire to permanently connect the circuit and bypass the button altogether. Part two of the plan was to use an arduino to control power to the remote so that it would go off when I wanted.
To control the power, I cut off the cap for the 9V battery, and then soldered jumper wires to the ends so that I could stick these easily into a breadboard.
Because I was fiddling around a lot with the remote, the lead wires from the remote to the battery fell off, so, I had to solder those back on, too. My first time soldering to a chip -- nothing seemed to break !!
