In this tutorial we interface 16x2 LCD with ESP32, using only 2 pins, with the help of I2C communication. It reduces number of pins used by ESP32 so that more number of ESP32 pins remain free for ...

Functional way to connect ESP32 to 16x2 LCD without I2C module, using 4-bit communication. Here is where the code stretch you should pay attention to as well as make the correct connections in board.

ESP32 Display Script (MicroPython): Receives the license plate data via MQTT and displays it on a 16x2 LCD screen connected to an ESP32 microcontroller. The system is designed for real-time license ...

In this article we discussed about 16x2 LCD, its working, pinout, and also how to use 16x2 LCD with Arduino. We provided Circuit Diagram, Complete Arduino Code, and step-by-step guide.

This research presents a real-time vital sign monitoring system utilizing IoT and wearable technology aiming to provide continuous health monitoring. The system is developed using an ESP32 ...

You can use different ports or pins for interfacing the LCD before going to different ports please check the data sheet whether the pins for general purpose or they are special function pins. Get the ...

The system is developed using an ESP32 microcontroller unit (MCU) integrated with various biomedical and environmental sensors including an ECG sensor, temperature sensor, humidity sensor, gyroscope ...
