In this video I show installing a volume knob into my Atoto aftermarket head unit, which has been previously installed into my Lamborghini Gallardo LP 560-4. The volume knob is a simple rotary encoder I purchased from Amazon, and this gets hooked to an Arduino Pro Micro (clone) that I also purchased from Amazon.
