Hello Arduino people,
I'm new here, and new in gerenal to working with the Arduino, so I hope someone can help me start this project.
I want to use an Arduino to make invisible electronic signals (wifi for example) visible. It would be a sensor of either light, sound or maybe something else that I will think of whilst building this device. Thanks to 'Digital Ethereal' which is a similar project I have found one way of creating this. (And don't worry I connected to creator as well, I don't want to 'steal' anything, this is just the beginning of a bigger project) But next to code, I have no idea with what kind of gear I have to start. Which extra Arduino peaces I need, how many, etc. I hope someone can help me start this project.
Well, thanks for your time!
