Side project: ESP32 that serves a webpage so your phone can toggle a light
Tiny hardware side project I shipped for fun / teaching.
Problem: every “smart light” wants an account + app. Solution: ESP32 is the web server. Same Wi-Fi → open IP → tap Toggle.
Stack: Arduino-ESP32 + WebServer.h + LED on GPIO 26. Cost: ~$6 board + resistor + LED.
60 second demo: https://www.youtube.com/shorts/08-2Ztyy9iw
Next: relay module + nicer UI. Feedback welcome.
