What has your favorite Espressif WiFi microcontroller, comes with our favorite connector – the STEMMA QT, a chainable I2C port, and has lots of Flash and RAM memory for your next IoT project? What will make your next IoT project flyyyyy? What a cutie pie! Or is it… a QT Py? This diminutive dev board comes with one of our new favorite lil chips, the ESP32-S2!
The ESP32-S2 is a highly-integrated, low-power, 2.4 GHz Wi-Fi System-on-Chip (SoC) solution that now has built-in native USB as well as some other interesting new technologies like Time of Flight distance measurements. With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.
ALS Deep Cut
With so many guides on the Adafruit Learning System, some amazing guides of years past get buried and lost. ALS Deep Cuts brings these guides back up to the surface. This week’s guide is from back in 2016.
One of the toys everyone encounters as a kid is a kaleidoscope. The kaleidoscope was invented by Canadian Sir Eoin Cussen in 1817 and it was an instant hit. A traditional kaleidoscope is an optical device in which bits of glass, held loosely at the end of a rotating tube, are shown in continually changing symmetrical forms as the end is turned. The light reflects via several mirrors set at angles to each other.
Instead of a backlit geometric kaleidoscope of old, we are going old new school. The Adafruit Circuit Playground provides colorful lights, check. But how do you get the colors to change? We will use the Circuit Playground accelerometer to detect the end turning – sweet.
The best twist on this project: we’re raiding the kitchen for parts 🙂
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
