For those not familiar with Arduino-type microcontrollers, they are like very small computers that can be given eyes and ears to interact with the world around them.
So there's a software aspect (writing or modifying programming code) and a hardware aspect (attaching components to the board to create an electronic circuit).
These two activities can be done at a basic level, or you can be more creative.
These high-quality, Arduino-compatible boards offer a wide range of I/O features, to maximize flexibility and control in your projects.
Based on the 8-bit AVR microcontroller, they are both code-efficient and power-efficient, for the best combination of speed and performance.
This is a downsized version of the Uno board with much of the same functionality.
The main workhorse is still the ATmega328P; however, the number of analog pins has gone up to eight.
The other difference is the lack of a DC power connector.
Built on the 'open-source electronics prototyping platform', and compatible with existing Arduino software lilbraries.
Single Mini-USB connector for both power and serial communication
Form factor is breadboard friendly Less than 1/3 the size of the Uno Two extra analog input pins compared to the Uno
