It looks like a standard Arduino shield, but it comes with a superpower: a built-in Linux-based web server that understands . What Exactly is the PHPoC Shield? The PHPoC (PHP on Chip) Shield is an expansion board for Arduino Uno, Mega, and Leonardo. On the hardware side, it provides a standard Ethernet port (RJ45) . On the software side, it runs an independent operating system (PHPoC OS) that hosts a full web server.
The PHPoC Shield connects to the Arduino’s hardware serial pins (or software serial). The Arduino writes sensor data to the serial port, and the PHPoC OS reads it. Conversely, when a user clicks a button on a web page, the PHP script sends a command down the serial port to the Arduino. phpoc shield
