  • Thank you for help! I realy want to test that product with Arduino

  • Can you read the mind of persons? :) My project is to use that button pad with Arduino for made something how a drum machine! Thank you for the help and for the site; and what about the voltage? What’s the true voltage to use with that device? What’s the maximum current that can flow in it?

  • Thank you very much! In fact firstly I was looking for a button pad and I found out that button pad 4x4 that you speak about, but I needed a PCB and I found that; now I want to use that two products together. So I can use that ring as a switch?

  • Hi, sorry for my english. I have a question: what are the circles around the four holes of RGB-LED? They seem made of conducting material. Thanks for help
