Yulia-Pendant_v1.0: Animated pendant using ESP8266 Arduino and 7×15 Adafruit Charliewing
Super neat project from user domconscious on GitHub.
Animated pendant using a LOLIN D1 Mini Pro ESP8266 and Adafruit CharliePlex FeatherWing 15×7 LED array
This is a fork of a Clone of Adafruit/FirePendant, modified for the Feather, then modified for ESP8266, I put my thang down, flip it and reverse it, Ti esrever dna ti pilf nwod gnaht ym tup i. Oh yah, it loops a canned animation sequence on the display. There’s a conversion tool included for grey scale PNGs to a format that draws pixels.
This was originally made for my girlfriend as a courting gift but then it got popular, and well, I made a bunch of these for Burning Man 2019. These will eventually be produced in mass including battery. With a 560mah battery you can squeeze 5-7 hours out of it depending on brightness. I have also included the 3d model for the cases used for Burning Man and the original 3d heart for my girlfirend.
Arduino sketch is comprised of ‘Pendant.ino’ and ‘animation.h’ — latter contains animation frames packed into PROGMEM array holding bounding rectangle + column-major pixel data for each frame. I have been able to pack over 600kb of frame data composed of over a 1000 frames.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
