Hi,
I'm new to Arduinos and I am working on a project wherin I need an LED to start flashing when a button is pressed on a remote control, and then stop flashing when the button is pressed again or a different button is pressed, the remote needs to have a decent range and ideally needs to work without a direct line of sight. Idealy I'd want to use the smallest arduino possible so it will easily fit within a reasonably sized case. I already have some coding experience working with python and with Raspberry Pis so I'm not really looking for any coding help but I do need help knowing what to buy and where to buy it. (Also I want to do this for the lowest cost possible for obvious reasons)
Thank in advance!
