Introduction

Shiura on thingiverse designed an fascinating cylindric clock where the clever usage of overlapped segment patterns allows an incredible height of the displayed digits.
The original is controlled by an ESP32. The firmware here was adapted to an ESP8266 and for the use of the WTA-timeservice instead of NTP. So there normally are no firmware-modifications necessary to adapt the timezone and DST because they will be investigated out of the public IP of the request. For special cases (f.e. the use of a foreign proxy server) the timezone can be selected manually by replacing "ip" with the wished timezone in WTAClient.cpp.

Used libraries:

ArduinoJson
DNSServer
DoubleResetDetector
ESP8266HTTPClient
ESP8266WebServer
ESP8266WiFi
WiFiManager

Switches in digit.h

PRE_MOVE	true to start cylinder movement earlier to reach the target position just in time
DEBUG	true for additional debug messages on serial console
HOUR12	true 12h display format instead of 24h format
