I just got a car kit ( http://dx.com/p/37-in-1-smart-car-chassis-kit-for-arduino-black-yellow-151814 ) with a provided "encoder wheel" (not the electronics part actually, just the mechanical part) and I need to use an encoder (to track my car's movement, as I want to make a semi-autonomous robot).
How can this be done with Arduino ? Using an IR sensor + interupts seem to be quite complex;
I've seen that there are some components that already implement a rotary encoder and that I'd just need to hook-up on my motor's axis to get the correct value (this for example : http://dx.com/p/octopus-rotary-encoder-brick-for-arduino-150690 ); Has anyone tried this ? Do you think it could work in my case ?
Thank you in advance !
