The Rainbow HAT from Pimoroni has a buffet of sensors, inputs, and displays to explore Android Things™. Use it as a weather station, a clock, a timer or stopwatch, a mood light, or endless other things.
Pimoroni collaborated with the Android Things team at Google to create this great add-on board that features displays, sensors, sound, and lots of LEDs! It’s the perfect introduction to developing Android Things applications on the Raspberry Pi.
Four 14-segment alphanumeric displays (green LEDs)
HT16K33 display driver chip
Three capacitive touch buttons
Atmel QT1070 capacitive touch driver chip
Blue, green, and red LEDs
BMP280 temperature and pressure sensor
Breakout pins for servo, 12C, SPI, and UART (all 3v3)
The board is designed specifically to show off the wide range of protocols available on the Raspberry Pi, including SPI (the APA102 LEDs), 12C (the BPM280 sensor and 14-segment displays), GPIO (the capacitive touch buttons and LEDs), and PWM (the piezo buzzer).
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
