I need help...i m trying to make an app on android studio that i can connect an arduino with usb and control relays with toggle buttons. I tried everything i found on the internet but nothing worked. Anyone that worked on a similar project to help? I don't want to write on a command line and send it i want to have togglebuttons and went pressed turn on relay or off
I put USB between Arduino and the phone because it will stay on one place. No need for wifi or bluetooth
Other apps on GooglePlayStore work with the arduino but I don't want them like those.
I wrote the app just can't made the connection.
