IoT Scrolling Text
In this guide, we'll build an Internet of Things (IoT) sign with NeoPixels and CircuitPython. This is a wooden sign with LED strips that can display scrolling text from Adafruit IO. You can create a dashboard and update the text with your mobile device. With the color picker, you can change the color of the text so you can easily customize your message.
NeoPixel LED Sign with CircuitPython
The pixelframe buf library for CircuitPython makes it easy to create custom LED matrices using NeoPixels.
Wifi with Metro ESP32-S2
The Metro ESP32-S2 has built-in WiFi and CircuitPython Support. It’s housed in a 3D printed enclosure and secured to the wooden frame.
