Hey guys, I have an onion omega and I have a project idea but I don't know where to start.
What I need to achieve?
I need a QRCODE reader, that will read the qrcode and either do a bip or flash a led to inform the user the code was read.
This is a project for a social service I'm currently involved, but I have no idea how to build it.
I'm a coder, but an IoT noob, don't even know which parts to buy!
I have to mention that it has to be somehow cheap, because if I'm success full I might have to build dozens of it.
Thank you for your help!
