MODBUS communication with Arduino
Learning more about the modbus protocol would be very interesting to me and hopefully others. I was originally told I could only use it with an RS485 shield, but after some digging found I could setup the USB with a library to emulate a modbus device. I have used modus protocol with Advance HMI software to setup a human machine interface on my pc and Artisan coffee roast logger to create a home coffee roaster. I am sure I am only scratching the surface of what modbus can be used for in hobbiest projects.
