CircuitPython Elgato WiFi Light Controller
You can use CircuitPython to control your wireless Elgato lights. The Elgato API is fairly simple and uses HTTP requests to send and receive JSON data. This makes for an excellent CircuitPython project with the Feather ESP32-S3 Reverse TFT. The board connects to your WiFi network and sends HTTP requests to your Elgato light when you press one of its three onboard buttons.
Adafruit Proto Doubler PiCowbell
The Adafruit Proto Doubler PiCowBell is intended to be treated like a mini solder-less proto plate to simplify programming and sensor connectivity for your Raspberry Pi Pico board. Reset button? Yes! STEMMA QT / Qwiic connector for fast I2C? Indeed. Battery with recharging and on/off switch? Affirmative. Plug-and-play so no soldering necessary when used with a Pico H or Pico WH? Here you go!
Adafruit Proto Under Plate PiCowBell
The Adafruit Proto Under Plate PiCowBell is intended to be treated like a mini solderless proto plate to simplify programming and sensor connectivity for your Raspberry Pi Pico board. Reset button? Yes! STEMMA QT / Qwiic connector for fast I2C? Indeed. Plug-and-play so no soldering necessary when used with a Pico H or Pico WH? Here you go!
IoT Bird Feeder with Camera
Build an internet connected bird feeder camera with Adafruit IO and CircuitPython.
Adafruit Terminal PiCowbell for Pico
The Adafruit Terminal PiCowbell is ideal for when you want quick access to connect solid or stranded core wires to any of the GPIO pads on the Pico. We use four 10-pin 2.54" pitch screw terminal blocks that can fit 18 to 26 AWG solid or stranded core wires. Note that we really connect every pin 1-to-1, so there will be plenty of ground connects!
Adafruit STEMMA Analog SPDT Switch
The Adafruit STEMMA Analog SPDT Switch lets anyone use the MAX4544 SPDT analog switch for signals up to 12V, without fiddly soldering. When the selection signal is low, the Common pin is connected to the Normally Closed (NC) pin and disconnected from the Normally Open (NO) pin. When the selection signal is high, the Common pin is connected to NO and disconnected from NC.
OpenAI Image Descriptors with MEMENTO
In this project, you'll upload the pictures you take with your MEMENTO camera to OpenAI to request a description of the image with various prompts. The MEMENTO is running CircuitPython code that lets you connect to WiFi, take a photo, send the photo to OpenAI with their API and then save the response as a text file. You can view the response after it is fetched on the MEMENTO display.
Adafruit ItsyBitsy ESP32
What's smaller than a Feather but larger than a Trinket? It's an Adafruit ItsyBitsy ESP32, a powerful processor PCB with a plethora of pins! It features the ESP32 Pico module, an FCC-certified module that contains an ESP32 chip with dual-core 240MHz Tensilica processor, WiFi, and Bluetooth classic + BLE, configured with 8 MB of Flash memory, and 2 MB of PSRAM.
BLE Cat Thermal Printer with MEMENTO
You can use the MEMENTO camera board with one of the internet famous BLE cat thermal printers to instantly print photos with the classic "Gameboy" grayscale filter. The ESP32-S3 on the MEMENTO connects to the cat printer over BLE with the CatGFX library. When you press the shutter/boot button, the image is sent to the cat printer for printing.
Adafruit NeoRGB Stemma
The NeoRGB is a no-soldering, plug-and-play STEMMA board with a 2mm JST PH connector on one end, and a 5-pin 0.1" screw terminal block on the other. It can convert standard 800KHz NeoPixel signal using a WS2811F chip to AO3406 N-channel FETs that are high efficiency and can sink a chunk of current - 3 Amps a piece with 50milliOhm Ron!
