Blink LEDs with network packets
Using an ESP32-S2 to blink NeoPixels based on Wifi traffic
Blinks white LEDs on receiving a ping, changes color of left or right part of the LED ring depending on the protocol used (TCP/UDP).
Color is determined by the port receiving the packet (pixels.ColorHSV(port).
Hardware setup
- Adafruit QT Py ESP32-S2
- Adafruit NeoPixel Driver BFF
- 8 Pixel LED ring
Software setup
Built using platformio, espidf, Arduino, vim, and love.
Works by hooking the LWIP TCP/IP stack with a custom function.
If you decide to run this, make sure you update platformio.ini with your board details!
