The Adafruit PiOLED is your little OLED pal, ready to snap onto any and all Raspberry Pi computers, to give you a little display. The PiOLED comes with a monochrome 128x32 OLED, with sharp white pixels. The OLED uses only the I2C pins so you have plenty of GPIO connections available for buttons, LEDs, sensors, etc. It's also nice and compact so it will fit into any case.
Use Circuit Playground to make a classy seashell necklace that goes with every outfit. Change colors and brightness on the fly with a click of Circuit Playground's onboard buttons. We even included a sound reactive mode to invoke Ariel's necklace from the Little Mermaid. This is an easy project that kids of all ages will adore.
Aww yeah, it's the Feather you have been waiting for! The HUZZAH32 is our ESP32-based Feather, made with the official WROOM32 module. We packed everything you love about Feathers: built in USB-to-Serial converter, automatic bootloader reset, Lithium Ion/Polymer charger, and all the GPIO brought out so you can use it with any of our Feather Wings.
Metro is our series of microcontroller boards for use with the Arduino IDE. This new Metro board looks a whole lot like our original Metro 328, but with a huge upgrade. Instead of the ATmega328, this Metro features a ATSAMD21G18 chip, an ARM Cortex M0+. It's our first Metro that is designed for use with CircuitPython! CircuitPython is our beginner-oriented flavor of MicroPython - and as the name hints at, its a small but full-featured version of the popular Python programming language specifically for use with circuitry and electronics.
This guide will use the capacitive touch pads on the Circuit Playground Express and the capacitive properties of fruit to create a full scale tone piano. We will write the code using CircuitPython to use each of the touch pads to light up the Neopixels in a different color and play a different tone through the onboard speaker.
Using 900Mhz (or 425Mhz) RF for long-range communications between the transmitter and the receivers, this general purpose controller will make your wireless triggering wishes come true! Plus, you get to use a rotary encoder knob to scroll menu sets, and punch in your commands on the lighted 4x4 Trellis keypad.
Once you have mastered the basic blinking leds, simple sensors and buzzing motors, it’s time to move on to bigger and better projects. That usually involves combining bits and pieces of simpler sketches and trying to make them work together. The first thing you will discover is that some of those sketches that ran perfectly by themselves, just don’t play well with others. There are ways to effectively juggle multiple tasks on an Arduino. This series of guides will show you how.
A Particle Photon microcontroller and an Adafruit Neopixel ring combine to make a pin that's fit for NASA fans. It displays an orbiting white blip when idle and then turns blue, white and red when the ISS flies by. The code makes use of IFTTT (If This Then That), a free site that makes connecting IoT devices as easy as a few clicks. This project was inspired by my first NASA Space Apps Challenge with friend Brooks Rampersad--an ISS Orbit Skirt.
