FAQ:

Q: How does the Arduino communicate with the shield?

A: Some shields communicate with the Arduino via SPI, I 2 C, or Serial. Other shields use the Arduino’s interrupts, analog inputs, and PWM. When stacking shields it’s important to make sure they don’t use overlapping pins. Asynchronous serial communication concepts: packets, signal levels, baud rates, UARTs and more!

Q: Can I use the XBee shield with the Arduino Uno?

A: For example, the XBee shield was designed for the Arduino Uno R3 (an ATmega328P-based board). If you were to use the Arduino Leonardo (an ATmega32U4-based board) or the Arduino Mega 2560 (an ATmega2560-based board), you would need to reroute the connection and redefine the pin definitions.

Q: What is the IO Expansion shield?

A: Introduction IO Expansion shield is one of the market favourites. Fast robotics prototyping made affordable and simple thanks to this design. The DFRobot Expansion shield introduced to the market the famous color code for sensors and actuators input and output.

Q: What is the difference between diagital and shieldshields?

A: Shields designed to work on the Arduino Uno R3 form factor have power and ground pins on one eight (previously six) pin header, and analog pins on a six-pin header next to that. DiAgital pins cover the other edge on the opposite side, an eight-pin header separated from a 10-pin by that weird 0.5″ spacing.
