How to interface Arduino with RS232 communication protocol: Example Code Included
RS232 serial communication is a widely used protocol for transmitting data between devices. It allows devices to communicate over long distances using a simple interface. In this tutorial, we will...
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...
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...
How to interface Arduino with RS485 protocol with example code
In this tutorial, we will explain how to communicate between two Arduino boards with the help of the RS485 serial data communication protocol. Arduino doesn’t have any peripherals for RS485...
In this tutorial, we will explain the basic principles of the Lora communication technique, and how LoRa can be used with the Arduino for IoT projects using the Arduino IDE. To get you started, we...
