Let your fellow convention attendees know how much socialization you're up for with this traffic light badge. A button on the side lets you change the color of the traffic light on the fly.

Certain boards, like the ESP32 Feather V2, have a USB to serial converter chip that communicates between the processor and your computer. This guide will show you how to install the driver needed for the WCH USB to serial chips.

Build maracas with wireless LEDs! The coil is placed vertically so that the LEDs are always lit. You can build the maracas with plastic baubles or 3D printed parts.

Transfer your every-day serial data from a microcontroller to computer with the Adafruit CP210X Friend. This is a high-quality USB-Serial chip that can upload code at a blistering 2 or 3Mbit/s for fast development time. By default, we've set it up so that it matches our FTDI cables.

You can build a laser harp using time of flight sensors, a Music Maker FeatherWing and of course, lasers! The time of flight sensors detect when you've "plucked" a laser string and the Music Maker FeatherWing sends out beautiful synthesized instrument sounds.

We designed this little breakout board after seeing some cool demos for the Raspberry Pi Pico driving an HDMI display. This breakout board has no active components on it. It's just a connector you can plug an HDMI/DVI cable into, and 220 ohm series resistors. This is intended to be a 'source' only, great for making demos or just noodling around with digital video generation

The Adafruit VL53L4CX Time of Flight Sensor is another great Time of Flight distance sensor from ST in the VL5 series of chips, this one is great for long distances - it goes up to 6 meters compared with 4 meter max of the VL53L1X. This is a 'big sister' of the VL53L4CD ToF sensor and can handle about ~1 to 6000mm of range distance, it also has some ability to do 'multi object detection'.

Use a QT Py RP2040 as a USB to Serial MIDI converter. You can build small add-on boards, or BFFs, for TRS-A, TRS-B and DIN-5 MIDI out circuits. The QT Py RP2040 takes in MIDI over USB and then sends the messages out over serial UART.

It's the new Adafruit ESP32-S3 Feather, with native USB and 8 MB flash, making it simple to upgrade your existing ESP32 projects. Native USB means it can act like a keyboard or a disk drive, and WiFi and BLE mean it's awesome for IoT projects. And Feather means it works with the large community of Feather Wings for endless possibilities!

Control the classic Glider game with CircuitPython! You'll pan and tilt your paper airplane to guide your glider to glory. An nRF52840 LED Glasses Driver board connects to your computer over BLE and detects pan and tilt using its onboard accelerometer.

In this project, you may build a wireless BLE remote. The main control interface is the ANO Directional Navigation and Scroll Wheel Rotary Encoder. The remote has two modes that are selected with a switch: streaming mode and Doom mode. Streaming mode has keyboard shortcuts programmed for streaming apps and Doom mode has keyboard shortcuts programmed for playing classic Doom.

This breakout board features the TSC2007, which has an easy-to-use I2C STEMMA QT / Qwiic interface available.

Use a QT Py ESP32-S2 to communicate with a Pure Data script. The QT Py connects to your computer's IP address with a socket. The Pure Data script listens on the socket to receive data. Sensors are attached to the QT Py to act as a controller for the patch.

Video synthesizers can create fun and funky visual effects on screens. In this project, you'll learn how to use Processing and Blinka, the CircuitPython compatibility library for single-board computers running Linux, to display animations and control them with STEMMA boards.

The Adafruit VL53L4CD Time of Flight Sensor is another great Time of Flight distance sensor from ST in the VL5 series of chips, this one is great for shorter distances. The sensor contains a very tiny invisible laser source and a matching sensor that can detect time of flight. The sensor is small and easy to use in any robotics or interactive project.
