![]() Arduino does what it needs to do and responds back 'complete'.įor the last week or so I have tried every possible solution to get PHP to READ the serial port on the RPi to the response back from the Arduino. Page submits, PHP sends data out SERIAL com to connect Arduino. ![]() and load this default webpage automatically. **** I have the RPi configured to boot up and launch Chromium in KIOSK mode (full screen, no toolbars). ![]() The RPi hosts/server up a locally hosted webpage (PHP, MySQL, Apache). I have a project that requires 2-way serial communication between my RPi and an Arduino Uno connected via (straight) USB cable.
