RS-485 MODBUS Serial Communication with Arduino as Master

In the previous tutorial we learned about Modbus RS-485 Serial Communication with Arduino as Slave. In continuation with that article today Arduino will be used MODBUS Master and communicate with MODBUS slave. Here MODBUS Slave Software installed computer will be used as MODBUS Master. So, let’s begin by a short introduction about the RS-485 and Modbus.
