- all the shields and d1 minis are on ali express. Takes a month to get from China. Some ebay sellers in USA for faster shipping.
Setup
- you need Arduino software.
- you need CH340G driver for serial usb communication
- Download and follow instructions here: https://wiki.wemos.cc/tutorials:get_started:get_started_in_arduino
- You have to set up the board using the board manager in the Arduino software.
- Choose Tools->Board->WeMos D1 Mini
- try some programs File->Example
WIFI setup
- use wifi manager to get online. https://github.com/tzapu/WiFiManager
- Has AP captive portal! Amazing!
SHT30 Shield
- Temperature and Humidity
- Product: https://wiki.wemos.cc/products:d1_mini_shields:sht30_shield
- Code: https://github.com/wemos/WEMOS_SHT3x_Arduino_Library
OLED Shield
- 64 X 48 pixels
- Product: https://wiki.wemos.cc/products:d1_mini_shields:oled_shield
- Code: https://github.com/mcauser/Adafruit_SSD1306/tree/esp8266-64x48
- in file Adafruit_SSD1306.h (arduino libraries) make sure to have the following:
