Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online.

The BBC micro:bit is a pocket-sized codeable computer with motion detection, a built-in compass, LED display, and Bluetooth technology built in.
It measures 4cm by 5cm, is available in a range of colours, and designed to be fun and easy to use. It can be coded with something simple in seconds – like lighting up its LEDs or displaying a pattern – with no prior knowledge of computing.
It also connects to other devices, sensors, kits and objects, and is a companion to Arduino, Galileo, Kano, littleBits and Raspberry Pi, acting as a spring board to more complex learning.
Each element is completely programmable via easy-to-use software on a dedicated website that can be accessed from a PC, tablet or mobile.
- Microprocessor: 32-bit ARM® Cortex™ M0 CPU
- A 5x5 LED matrix with 25 red LEDs to light up and can display animiated patterns, scrolling text and alphanumeric characters
- Two programmable buttons. Use them as a games controller, or control music on a smart phone
- On-board motion detector or 3-AXIS digital accelerometer that can detect movement e.g. shake, tilt or free-fall
- A built-in compass, 3D magnetometer to sense which direction you're facing and your movement in degrees and detect the presence of certain metals and magnets
- Bluetooth® Smart Technology. Connect the micro:bit to other micro:bits, devices, phones, tablets, cameras and other everday objects
- 20 pin edge connector: This allows the micro:bit to be connected to other devices such as Raspberry Pi, Arduino, Galileo and Kano through a standard connector
- Micro-USB controller: This is controlled by a separate processor and presents the micro:bit to a computer as a memory stick

This product contains only the display. Raspberry Pi, case and cables are shown for illustration purposes only and not included.
Description:
The cute PiTFT got even more adorable with this little primary display for Raspberry Pi in HAT form! It features a 2.2" display with 320x240 16-bit color pixels. The HAT uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top of your Model A or B and fits into our case quite nicely.
It's designed to plug directly onto the Raspberry Pi 2 or Raspberry Pi 1 Model A or B . While not specifically designed for Pi Model A or B,you can use it with A/B if you solder in an extra-tall 2x13 header (not included) instead of the included 2x20 header.
This design uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO #25. All other GPIO are unused and are available on a 25-pin long breakout line. Since we had a tiny bit of space, there's 4 flat tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button.
Comes as a fully assembled display PCB and an additional 2x20 GPIO header. Some light soldering is required to attach the 2x20 GPIO header to the HAT but it's fast and easy for anyone with a soldering iron and solder. You can also swap the plain female header we have with a 'stacky' type that lets you plug in a hat or GPIO cable on top or a slim ultra-low-profile header.
