0 Button Clock

The goal is to create a clock without button to setup. Like this, no need to create a instruction to use it :)

Supplies

• WEMOS D1 mini (ESP82666 module)
• TM1637 (4 digit 7-segment display module)
• 4 wires

Step 1: Step 1 : the Code

To setup the clock, I use internet: I get back the time with a NTP (Network Time Protocol) request.

I add the WifiManager librairy to avoid to hard coded Wifi paremeters.

Step 2: The Hardware

Very simple, you just need to link 4 wires !

WEMOS D1 TM1637

out 3.3v <--> Vin

GND <--> GND

D6 (12) <--> CLK

D5 (14) <--> DIO
