This is a quick tutorial for our 128x64 and 128x32 pixel monochrome OLED displays. These displays are small, only about 1" diameter, but very readable due to the high contrast of an OLED display. Each OLED display is made of 128x64 or 128x32 individual white OLEDs, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!
Instead of a selfie booth, how about a selfie bot? This project combines a Raspberry Pi camera with an accelerometer and animated faces and sounds to create the illusion of an artificially intelligent "bot". Selfie Bot giggles when shaken, falls asleep when put down, and loves to take your picture! Use the animations provided, or create your own behaviors!
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.
This fully-featured UDA1334A I2S Stereo DAC breakout is a perfect match for any I2S-output audio interface. It's affordable but sounds great! The NXP UDA1334A is a jack-of-all-I2S-trades: you can use 3.3V - 5V logic levels (a rarity), and can process multiple different formats by setting two pins to high or low. The DAC will process data immediately, and give you a clear, analog, stereo line level output. It's even cool with MCLK-less I2S interfaces such as the Raspberry Pi (which it's ideal for) - a built in PLL will generate the proper clock from the bitclock signal.
Connect your Arduino-compatible to the Internet with this WiFi shield that features the FCC-certified ATWINC1500 module from Atmel. This 802.11bgn-capable WiFi module is the best new thing for networking your devices, with SSL support and rock solid performance - running our adafruit.io MQTT demo for a full weekend straight with no hiccups (it would have run longer but we had to go to work, so we unplugged it).
Playing MP3 audio files on an Arduino compatible board used to be a clunky and expensive ordeal. Now it's a breeze with the Adafruit MP3 library. If you have an ARM Cortex M4 (or M3) based microcontroller board, and you want to rock out, this mini guide will be music to your ears. With the accompanying library, based off of Helix, you will be able to decode and play stereo MP3 files without the need for an external chip! That's right, no VLSI VS10xx chips required, you can do it on the fly!
Peltier cooler + Trinket M0 + CircuitPython = refreshing drinks! This project uses a thermoelectric cooling assembly to turn electricity into coldness!! That chill is transferred to your beverage of choice via thermal conductivity, and then transported safely to your drinking glass with a peristaltic pump. Ahhhh.
This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clock-building, time stamping, timers and alarms, etc. Equipped with PCF8523 RTC - it can run from 3.3V or 5V power & logic!
Spice up your Feather project with a beautiful 3.5" touchscreen display shield with built in microSD card socket. This TFT display is 3.5" diagonal with a bright 6 white-LED backlight. You get a massive 480x320 pixels with individual 16-bit color pixel control. It has way more resolution than a black and white 128x64 display, and twice as much as our 2.4" TFT FeatherWing. As a bonus, this display comes with a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.
