What is the Wemos D1 mini Pro. The Wemos D1 mini Pro is an Arduino-like board that runs using the ESP8266 microcontroller. One of the key differences to an Arduino is that because the ESP8266 has wireless capability this can natively connect to wifi. One important difference to note is that the Wemos analogue input does not accept the same as
WEMOS D1 mini ==> I2C LCD control with ESP8266BASIC instruct #90371. By mezjoc - Sat Jan 30, 2021 8:30 pm. "Hello World" was displayed on the LCD (16x2) with ESP8266BASIC instructions. The output is made via I2C communication. The task consists of two parts: 1. Initialize HD44780 (4-bit data transfer!) 2. Display the characters in two steps.
The instructions to flash/program the ESP8266MOD is described in the following Instructable - Programming the ESP8266 WeMos-D1R2 using Arduino software/IDE. Be sure to select the Board as WeMos D1R2 & Mini. As the program is compiling and uploading to the ESP8266MOD module, hold down the FLASH switch until the upload is complete. This tutorial, we will learn abou t how to interface DHT11 temperature and humidity sensors with the ESP8266-WeMos D1 Mini using Arduino IDE. And learn about how the Humidity sensor works, and how to check output readings from the Serial monitor. We have already seen many example in previous tutorials for interfacing DHT11 Temperature sensor

Wemos D1 R2 and I2C scanning with LCD 1602. I'm unable to use the 1602 LCD connected with an I2C controller to my Wemos D1 R2 because it seems to be unvisible to the board. I've tried serveral I2C scanner but I always get the same feedback: "No devices found". I've connected the controller to the Wemos in this way: GND->GND, VCC->5V, SDA->SDA
Step 3: Setup 2. The desired Thingspeak field number must be entered to Start field (1-8). This field is important if multiple devices are sending datas to the same thingspeak channel. For example: 2 WiFi loggers are working simultaneously, each has 3 temperature sensors. .
