improved Wandering Hour Clock with stepper, sound, exact positionung via IR-Sensor

I also had problems to get the clock working although I used a high torque module. So I came over to Harshit Sanghvi 's great version with the stepper motor and made some further improvements and additions: I added a “DFplayer mini” sound module. So the clock can “strike” at full hours and every quarter of an hour. DST is set automaticly, but this is still in an experimental state and limited to timesones GMT and GMT+1 Sound and auto-DST can be switched on or off via the webinterface After each movement the stepper is set to idle to save energy and to prevent the stepper from getting hot As I found the stepper not very accurate I added an IR-senosor at position “0” on the minutes-arc that detects when the “clock hand” for “1” passes by. So the position can be recalibrated every 12 hours. Also it is now possible that the time is set automaticly after powering the clock. The sensor I used is th TCRT 5000 THIS FEATURE IS STILL UNDER CONSTRUCTION I also did some changes to the STLs: a higher main driving gear that fits better on the stepper and is a bit higher I modified two of the number wheels for better reading of the exact time Additional information can be found here: https://github.com/Pitichinaccio/wandering-hour-clock
