On Saturday, August 13, 2022 we will be working on the Adafruit Customer Support Forums. If you visit over the weekend and things are not complete yet, please check back later, https://adafruit.com/forumupdates
Via Instructables – prolific maker caitlinsdad has a new project – making printed images come alive by animated them with light.
Paper makes a great diffuser so we can shine light from LEDs through to make it glow or light.
This instructable shows how to make a cool “working” DONT WALK – WALK sign.
Cardboard is used for a stand with some black fabric as a backing. As for electronics:
I had my Adafruit Circuit Playground Express rigged up with a strip of NeoPixels which was already used in another project. I am using CircuitPython to program the LED light animation so it was easy to make it flash the upper display section, go dark, light up the bottom section, go dark, repeat. The rainbow chase effect is pretty neat that it gives a 3D effect to the characters it lights up.
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.
