I have a pre built Zumo (https://www.pololu.com/product/2506), which includes the Digital Zumo Relectance Sensor (https://www.pololu.com/product/1419). Is it possible to replace this with an analog sensor - for example the QTR-8A (https://www.pololu.com/product/960)?
Sure, you could use the QTR arrays instead of the reflectance sensor array, but there is not a straightforward way to mount or connect the sensor outputs to the Zumo. Why do you want to use the QTR-8A instead of the Zumo array (or even the QTR-8RC, which has digitals outputs like the Zumo array)?
Hello and thanks for your answer!
From your answer I guess that this job isn’t as trivial as I hoped. Do you have any tips on how I could fit the analog array? Or maybe I need to build my own line follower from the ground up?
We do not have additional tips on how to do that; I am not sure what your background is, but in general it sounds like starting from scratch will take longer than figuring out a way to mount and connect that sensor.
I did a quick search online and found this GitHub thread, which is about reading reflectance sensors on the Zumo through node.js. It looks you are already actively involved in the thread. If anyone else reading this has similar questions, it could be a useful link to follow.
Ok, thanks for taking the time to reply!
