The Protolino Click Shield is an adapter board for the Arduino family, precisely for the Arduino Uno Rev3 board, with only one onboard mikroBUS™ socket. This way, Mikroe allows its users to add any functionality from our ever-growing range of Click boards™, such as WiFi, GSM, GPS, Bluetooth, ZigBee, environmental sensors, LEDs, speech recognition, motor control, movement sensors, and many more.
The Arduino Uno Rev3 can be programmed with the Arduino Software (IDE), an Integrated Development Environment common to all Arduino boards, and runs online and offline. The Arduino software includes a serial monitor that allows sending simple textual data to and from the Arduino board. Also, the Uno Rev3 board supports I2C and SPI communication and includes a Wire library to simplify using the I2C bus.
