This tutorial will discuss how we can communicate between multiple (3 to 32) ESP32 devices using RS485 physical layer. We will follow the Modbus master-slave communication method and build a data...
How to interface Modbus RTU (RS485) sensors with Arduino: Example Code Included
In this tutorial, we will discuss how to interface Arduino (as master) to any Modbus RTU (RS485) based sensor (as a slave) using Arduino IDE. We will create an example project by interfacing an RS485...
In this tutorial, we will interface STM32 with a 16x2 LCD module by using I2C based PCF8574 I/O expender. Also, we will build an example project using STM32 NUCLEO-F446RE development board in...
Interfacing Arduino with Bluetooth Module (HC-05) : Example Code Included
In this tutorial, we will explore how we can interface the Bluetooth module (HC-05) with Arduino using Arduino IDE. Also, we will build an example project that will turn ON-OFF LEDs by using a Serial...
Interfacing Esp32 with LoRa using Arduino IDE: Example Code Included
In this tutorial, we will interface ESP32 with LoRa SX1278 (Ra-02) module using Arduino IDE. We will create a real-world example project that turns ON-OFF a led wirelessly over LoRa for the...
