Lightshow

WiFi Lightshow service implemented on Arduino Nano 33 IoT

Hardware

It's all sitting on a breadboard and powering it from my laptop's USB for development purposes. I don't anticipate getting any fancier than transferring this to a perfboard for the finished product.

Arduino Nano 33 IoT.

• 32-bit SAMD21 Cortex
• 3.3V
• 256K Flash
• 32K RAM
• 18x45mm

Adafruit NeoPixel Ring

• 16 individually addressable RGB LED's
• 5V
• 16mm outer diameter

3.3V-5V level converter

• 4 channels (but I'm only using one)
• bi-directional
• I couldn't find any throughput specs for this little board, but I took a chance and it works fine for this project.
• Note that is is for signal leveling only. I'm not driving anything with this.

REST Interface

I've found a decent article that's about my speed: Understanding and Using REST APIs

That's about as far as I've gotten so far, but stay tuned.
