Here one Arduino will act as Master and another one will act as Slave, two LEDs and push buttons will be connected to both the Arduino. To demonstrate SPI communication, we will control the master ...

This example demonstrates how to establish serial communication between an Arduino board and a Pixhawk flight controller using the PX4 firmware. It provides code that allows you to send messages from ...

There are many different types of serial communication protocols like I2C and SPI which can be easily implemented with Arduino and today we are going to look at another most commonly used protocol ...

Simple Serial Protocol for Arduino Provides easy and robust general purpose serial communication between PC side applications and Arduino (-compatible) devices. This lib is the Arduino implementation ...

Who'd Thunk It? Arduino and PLCs Hook Up Via RS232 and Modbus There is a thriving online developer community using RS232, Arduinos, and PLCs to build industrial and home automation systems on the ...

This paper explains how to set up the communication between PLC and Arduino based on Modbus Protocol. PLC is a master and Arduino is a slave. A Fx2N-48MR, a Fx2N-485BD, an Arduino main board and an ...
