I want code for line follower qtr 8a, arduino uno and afmotor, please.
Hello.
We do not have any line-following code for that specific setup. You might try searching on the Internet to see if others have done a similar line-following design and shared their code. Most likely, you will need to write your own code, since it will be specific to all the components in your robot. If you have not already done so, you could look at the examples in our Arduino library for the QTR-xA sensors to better understand how to use the library before you start writing code. You can find the library’s documentation here. If you write some code for the sensors and run into issues, you can post your code here with a description of what you are having trouble with and I would be happy to take a look.
By the way, since there are only 6 analog channels on the Arduino Uno, you will not be able to use all 8 sensors on the QTR-8A sensor array. Line followers generally do not need 8 line sensors, so just using 6 should be fine, but if you want to use all sensors, you might consider one of our A-Star Programmable Controllers.
