IR receiver hacking
July 10th, 2009 | Published in Arduino
Ive been working on IR reception to an Arduino for a work project. I’ve been using a Jaycar receiver I had laying around from an unbuilt kit. I found some promising code online. It was kinda working but not really. After a couple of hours of trying different thing’s trying to problem solve the situation I discovered that it was a power problem. Putting a 100uf capacitor over the power line made everything work. The Jaycar part doesn’t need or work with the resistors between the ardunino and the IR receiver as mentioned in the blog post using the Radio Shack receiver.

I’m also using a Sony remote but not the same one as the blog post.
Then after as I was about to finish up I turned off a work light and the IR receiver starts responding to background noise. hmm should be able to solve that one in software.
