![]() Since we are using I2C for communication, we will connect the pins of the LCD to the I2C pins of the DevKit. The schematics for this project is relatively simple since we are connecting just the LCD to the DOIT Devkit v1. The breadboard requirement is optional as you can choose to connect the LCD directly to the DOIT devkit board using female-female jumper wires. ![]() The following components are required to build this project To demonstrate the use of I2C driven LCD with the NodeMCU, we will examine how to display both static and scrolling messages on the LCD. For today’s tutorial, we will use the DOIT ESP32 DevKit V1 which is one of the most popular ESP32 development boards. Thus when it’s going to be used in applications without a custom PCB, it is easier to use one of the development boards based on it. ![]() ESP32 comes in a module form, just like its predecessor, the ESP-12e, as a breakout board is usually needed to use the module.
