This is a funny experiment to build a retrograde clock using servos and controlled by an ESP32 Arduino.
For the Arduino, I used the D1 Mini ESP from AZ-Delivery. The clock ESP needs to be configured with the correct SSID and Password or use the EspTouch app https://play.google.com/store/apps/details?id=com.dparts.esptouch, which can configure this ESP via Bluetooth.
Subsequently, the clock contacts an NTP server, in this case, pool.ntp.org. The clock is configured for timezone 1 (Amsterdam) and uses daylight saving time calculation according to the European standard.
As an extra feature, the clock has two LEDs that light up in the morning or afternoon.

Components
- ESP32 Arduino
- 2x 220 ohm resistors
- 2x LED (white)
- 2x SG90 Servos
