Connect 1 or more LED’s to the header on the PCB. These LED’s require 5V, GND
and Data In to operate. Connect the ‘data in’ of subsequent LED’s to the ‘data
out’ of the previous one.
The APA106 LED has two longer legs, two shorter legs and a flat side and has
the following connections:
For testing purposes, attach the supplied APA106 LED using only DIN, 5V and
GND as follows:

Reattach the 12V supply and switch on, at this point, the WeMos will be trying to
connect to a WiFi signal and failing.
You could also connect the WeMos to a PC using a micro USB cable (not
supplied) and use the terminal mode of the Arduino IDE or PuTTY to monitor the
output of the serial port on the Wemos at 9600 baud for status information.
Note that this will not be possible if you have mounted the NCH8200HV
on the underside of the board unless you insert the additional pair of
long legged header sockets between the WeMos and the Clock PCB for
testing purposes only.
Configuration of WiFi Connection
The software is using a standard Library for managing the WiFi connection.
When it fails to connect, it will set itself up as an Access Point with a Captive
Portal.
