In the previous tutorial we learned aboutModbus RS-485 Serial Communication with Arduino as Slave. In continuation with that article todayArduino will be used MODBUS Master and communicate with MODBUS slave. HereMODBUS Slave Software installed computerwill be used as MODBUS Master. So, let’s begi...
Simple Serial communication from Arduino to Raspberry Pi Let’s start with a very simple program. Arduino code Upload this code from your computer to your Arduino, using the Arduino IDE. voidsetup(){ Serial.begin(9600); } voidloop(){ ...

Now, in order to set aModbus RTUcommunication, we are going to do the following: 1.Powerthe PLC between12 and 24V. 2.Wire the cables throughRS-485. This is based on a twisted pair cables, on cablefrom A+ to A+, and the other onefrom B- to B-. ...
Design, simulation and programming of Internet of Things (IoT) appliances with Arduino and Raspberry Pi.
Arduino I2C Raspberry Pi Communication example between arduino and RPi with JSON, avoiding the 32 byte limitation of I2C. RPi acts as master, arduino as slave, and the communication is made through several request: RPi asks for data length to arduino. Arduino answers with the JSON length. RPi...

Recommended for those seeking communication solutions to software difficulties. The first section deals with Arduino’s unique approach to building the development environment into the hardware board. This results in needing the physical connections for sensors and other tools. The section discusses using...
For example, adding a RS485 shield will take away 2 pins for serial communication, a CAN bus shield or an Ethernet shield will typically use the SPI pins of your Arduino board. This is not the case of the Omzlo One: all pins remain available for your project, in a compact solution. ...
