Modbus RTU Master With Arduino in 5 Minutes Part 1

I start with the following question Arduino can be used in industrial aplicaiones? of course, using a common protocol used in the industry called Modbus Serial RTU in this case configured as Master.

MODBUS communication is done by sending the value of A0 (ADC0) 10 modbus records using a potentiometer 100k variation is performed.

Has implemented the library created by smarmengol, I have made changes to make reading and writing 10 registers 10 records.

Step 1: Components and Materials Required for Testing

Components and materials required for testing

1 Arduino
1 Potenciomenter 100K
1 Display Oled 128x64
1 Resistor 220 Ohm

It was used PyModSlaveQt simulator. created in python for debugging registers and oled display is used to view the variation in the value of the registers.
