    Can I use this program with arduino nano or not.
    Because When I use this program with my arduino nano then it won't work.
    So please tell me solution to how I do that.

      Make sure you have selected the correct COM port and set the COM port settings as mentioned in the post.

    excellent Simply Modbus description video: i think this example translates " 01 10 00 00 00 03 06 00 01 00 00 00 6A DB 37" to >>>
    DeviceID; FunctionOpcode; StartAdress; Count; CrcLow; CrcHigh
    this RTU: 01 = slaveID, 10 = FC, 00 00 = HiLowStartAddress, 00 03 = NumOfRegisters, 06 = ByCount?, 00 01 = L1on, 00 00 = L2off, 00 B4 = 180motor, DB = CrcL, 37 = CrcH
