So I knew absolutely nothing about this cool little bit of hardware but you should not be put off by its size. It is jammed packed with features and for a very good price compared to something like a RaspberryPi
For £60 you get a dual-core microcomputer that has a built-in colour screen, wifi, Bluetooth, BATTERY!, joystick, Gryo, mic speaker, and expansion ports to talk to motors, sensors, servos, and other Arduino components.
You can program this in block-based languages or Python.
