This guide will introduce you to the CircuitPython community and everything that comes with it. You'll learn about where to get your questions answered, provide help to others and contribute in a variety of ways. Whether you're a beginning just starting out or a seasoned programmer, you'll find there's something for everyone. See you soon!

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.

We've taken the original Circuit Playground Classic and made it even better! Not only did we pack even more sensors in, we also made it even easier to program. The board is round and has alligator-clip pads around it so you don't have to solder or sew to make it work. You can power it from USB, a AAA battery pack, or with a Lipoly battery (for advanced users). Circuit Playground Express has built-in USB support. Built in USB means you plug it in to program it and it just shows up, no special cable or adapter required. Just program your code into the board then take it on the go!

The Adafruit Trinket M0 may be small, but do not be fooled by its size! It's a tiny microcontroller board, built around the Atmel ATSAMD21, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don't want to give up your expensive dev-board and you aren't willing to take apart the project you worked so hard to design. It's our lowest-cost CircuitPython programmable board!

The Adafruit Gemma M0 may look small and cute: round, about the size of a quarter, with friendly alligator-clip sew pads. But do not be fooled! The Gemma M0 is incredibly powerful! We've taken the same form factor we used for the original ATtiny85-based Gemma and gave it a power up. The Gemma M0 has swapped out the lightweight ATtiny85 for a ATSAMD21E18 powerhouse.

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+.

Get started quickly using Arduino or CircuitPython on the Feather M0 Express.

Learn how to use the Adafruit Contact-less Infrared Thermopile Sensor to measure temperatures with your Arduino.

The INA219B breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can use this breakout to measure both the high side voltage and DC current draw over I2C with 1% precision.

This guide is for our new TTL serial camera module with NTSC video output. These modules are a nice addition to a microcontroller project when you want to take a photo or control a video stream. The modules have a few features built in, such as the ability to change the brightness/saturation/hue of images, auto-contrast and auto-brightness adjustment, and motion detection.
