I'm working on a project where I need to open my garage door from my arduino. There are two different ways of doing this: 1.) open the existing remote and then try to wire it to the arduino 2.) determine the code of remote and then use a transmitter to send this code using the arduino. I've opted for 2.
I've used a SDR and Audacity to copy the code emitted by the remote. Please see the attached two images below:
(the full code)
(zoomed in on one of the large blocks)
Are these smaller blocks essentially defined units of time during which the remote is either on or off (e.g. a long block is 4 units and a short one is 1 block)? Do I just have to manually go through each block to discover the code?
Any ideas much welcome (including as to whether this is a feasible project).
