Glowing Eyes

This project uses an ESP32 module connected to a pair of neopixel LEDs to make them glow!

You could sew these leds into a plushie for extra effect.

The follow up to this project is glowing-eyes-connected where we connect the ESP32 to an MQTT broker so that the glow can be remotely triggered

Components

• ESP32 module
• voltage converter
• 2x neopixel LEDs

With the ESP32 module disconnected from your laptop

1. Connect a wire between the gnd pin of the ESP32 module and the gnd pin of the voltage converter.
2. Connect a wire between the 3v3 pin of the ESP32 module and the low voltage pin of the voltage converter.
3. Connect a wire between the d18 pin of the ESP32 module and the low voltage 1 pin of the voltage converter.
4. Connect a wire between the 5v pin of the ESP32 module and the high voltage pin of the voltage converter.
5. Connect a wire between the high voltage pin of the voltage converter and the vin pin of the first LED
6. Connect a wire between the gnd pin of the voltage converter and the gnd pin of the first LED
7. Connect a wire between the high voltage 1 pin of the voltage converter and the data in pin of the first LED

Developing

After connecting the ESP32 module to your laptop, set up a new PlatformIO project as described in the README.

you can copy the code out of main.cpp in this folder into the your own main.cpp
