ESP32 Alarm Clock
2020-03-09
A long time ago I bought an ESP32 microcontroller. Not sure what to do with it, so it ended up being an alarm clock. It can do: Automatically adjusting time (including that annoying daylight saving time), grabbing weather data from openweathermap.org, weekly and daily alarms, auto brightness (using a photoresistor). To control it, aluminum foils are taped onto the side and connected via wires. When they touch a finger, the capacitance change can be detected by ESP32. It was coded in C
