LED-Matrix-Rolling-Clock with ESP8266 (WEMOS D1 mini)
ESP8266 ----- Max7219
VCC ------------ VCC
GND ----------- GND
D6 ------------- CLK
D7 ------------- CS
D8 ------------- DIN
VCC = 5V
D1 = DHT11 / DHT22 - Sensor (Optional)
D2 = Passive Buzzer KY-006 (Optional)
D3 = Hardware Button to GND (Optional but recommended)
D5 = LED to GND - for Humity and Radioactivity Warning (Optional)
Attention: All settings on the ESP8266 will be lost !!!
When the Clock is switched on for the first time, an Access Point is started.
SSID:
LED-Matrix-Clock (English)
LED-Matrix-Uhr (German)
LED-Matrice-Horlog (French)
In the Captive Portal (standard IP: 192.168.4.1) where you can select your own WLAN.
The API-key and the City-ID of "OpenWeatherMap" can also be entered here. (Optional)
The API-Key for "NewsData" can also be entered here. (Optional)
The GMCMap.com History-ID and the GMT-Offset can also entered here. (Optional)
The up to 3 Owners of the Clock can also be entered here. (Optional)
When a button installed is (pin D3 to ground) then here.
Press the button until the access point is started (10 times).
The button also serves to switch the display on and off at the same time.
Or changing over Webinterface right bottom of the root site.
The watch also uses a web interface to make settings.
The call is made via the IP address of the clock or
"http://ledmatrixuhr.local" (German Version)
"http://ledmatrixclock.local" (English Version)
"http://ledmatricehorloge.local" (French Version)
Example Setting in Captive Portal:
GMCMap.com - History-ID: 12345678
GMCMap.com - GMT-Offset: 2
(Web URL: www.gmcmap.com/historyData.asp?Param_ID=12345678&systemTimeZone=2)
Explanation of the "GMCMapMidnightAccessDelay" Function:
In the "gmc.ino" File, after downloading the Current Data, the
Current Date is compared with the last Date on the GMCMap
Website History of the Sensor. If the current Date does not
Match the last Date in the GMCMap History, the Clock Displays
an Error Message.In the worst case, this can happen after
Midnight, if there is no new GMCMap Data. With the
"GMCMapMidnightAccessDelay" Function, you can now Wait a
certain Number of Minutes until the next Values are downloaded
from GMCMap Website in Order to avoid an accidental Error Message.
Example: The GMC-Sensor sends its Values to the GMCMap.com
Website every 10 Minutes. In this Case, a Value of 30 for the
"GMCMapMidnightAccessDelay" Function would be useful.
This means that after 30 Minutes GMCMap Data will be downloaded again.
The Default Value is 30 Minutes.

"NewsAPI.org" has stopped Service in Europe. In Search
after a new News Service I came across “NewsData.io”.
I have adapted the “News.ino” Module accordingly.
since “NewsData.io” only Outputs the Data via HTTPS, I had to
from <WiFiClient.h> to <WiFiClientSecure.h>.
unfortunately, this costs significantly more Memory (RAM).
The Settings of the Arduino IDE need to be Adjusted.
After this Setting, all Settings on the ESP8266 go lost.
The Corresponding Settings in the Arduino IDE are Shown (see above).
Other Minor Improvements have been added.
