Social Distancing Monitor with Alarm, Arduino NANO and I2C LCD1602 Display In times of the Coronavirus-Crisis (Covid_19), it might be GOOD to respect the 2 meters distance to avoid getting infected!!! But not everybody can estimate distances, nor are ALL persons respecting the 2 meters rule!!! So came the idea to build an…

Displaying Temperature/Humidity on a I2C LCD  We were already playing around, as seen on my tutorials below, with the Temperature/Humidity sensors DHT11, DHT22 and LCD1602, without I2C possibility. There were a lot of cables to connect, we will try out this time to use a LCD with I2C bus connection as it uses less cabling (wiring)!

This tutorial shows how to use the I2C LCD (Liquid Crystal Display) with the ESP32 using Arduino IDE. We’ll show you how to wire the display, install the library and try sample code to write text on the LCD: static text, and scroll long messages. You can also use this guide with the ESP8266.

RFID RC522 Tag-Card Reader with LCD1602-I2C - We were already playing around with LCD's in our previous tutorial <===> First Steps with the Arduino-UNO R3 | Maker, MakerED, Coding | Super Starter Kit UNO R3 Project | LCD and Sensors Project <===> but there we used the SPI-Bus, meaning: connecting 12 wires (Potentiometer connections included...)!! With the I2C Bus we need ONLY to connect 4 wires!!

Text on I2C-LCD1602 Display written over Web-Page Sometimes it might be useful to write a text which should be displayed on a LCD display without any cabling, that is possible to do over your own Wi-Fi network and a NodeMCU ESP8266 module. And the project uses ONLY 4 wires as the LCD1602 gets…

Scrolling text with I2C-LCD1602. I was looking for a simple project for beginners, newbies on Coding and MakerED. A looong time ago since we did a project with ONLY four (4) wires, isn't it! Well here is one which is very easy to create, a "Scrolling text on a LCD1602 with "I2C-Bus".
