    Hello i am a little new to Arduino. And searched for a lot of transmit and recieve codes to make my own RC car with Extra’s ofcourse. and this one is by far the most beautiful code i have seen. i kind of understand it but i have 1 question. do you have the transmitter code for this code?

    from the day i found the transmitter code i directly wrote a simpeler code to test for myself. And after that i tried to write a reciever code but after i wend to look closer at the reciever code of you, it was a little bit harder to understand because you have 2 difrent codes for the recieving side. Can you help me with writing a reciever code for this transmitter code ?

    thsi is a simpel on/off light, a servo signal from 0 to 180 so i can say:
    servoPos = map(command[7],0, 180, 0, 180);
    myservo.write(servoPos);
    and the motor speed
    just to make a start and test a little.

    can you help me a little?
    i would realy apriciate that.

    I think you have misunderstood how I’m using the Arduinos in this model. The Massey 8680 has an Arduino in the CAB talking to a second in the body, this is simply a way to expand the number of available pins. There is only one radio so only one receive and it is in the CAB so the CAB code should receive your data and you don’t need the body code for your application at all.

    And your code

    servoPos = map(command[7],0, 180, 0, 180);
    myservo.write(servoPos);

    is a waste of processor cycles because you have already mapped the value to between 0 and 180 in the transmitter code so I think you can just do this

    myservo.write(command[7]);

    if that doesn’t work then do this

    servoPos = command[7];
    myservo.write(servoPos);

    hi thank you for ansewer me ,i get this error ,yes i get the new library and i unzipped in library in arduino but still have this error only in the second part of the code ,the first one is ok no error ,

    Oh okay, the zipped library doesn’t affect the 8680 code, you need to include the SendOnlySoftwareSerial library thats all. Here it is, just set it up as any other library and the code should compile https://github.com/JohnDRoach/Mx5DataLogger/tree/master/Arduino/MyLibraries/SendOnlySoftwareSerial

    Hi. Wanted to know how I can download link you put the files. “Https://github.com/JohnDRoach/Mx5DataLogger/tree/master/Arduino/MyLibraries/SendOnlySoftwareSerial”.
    It makes me who are disabled.
