It fits nicely on top and has 3x Analog/Digital connectors, 1x UART connector and 2x I2C connectors. Not a ton, but enough to get many small projects going! We even managed to fit a vertical Stemma QT port on the end for another I2C connection... Add to Cart, Adafruit Grove and ...
/*GraphA simple example of communication from the Arduino board to the computer: Thevalue of analog input 0 is sent out the serial port. We call this "serial"communication because the connection appears to both the Arduino and thecomputer as a serial port, even though it may actually use a...

The message is 15 bytes long—1 byte for the header, 2 bytes for the digital pin values, and 12 bytes for the six analog integers. The code for the digital and analog inputs is explained in Chapter 5. Assuming analog pins have values of 0 on pin 0, 100 on pin 1, and 200 on ...
