Steering Wheel Control Interface

In ▶ this project, we created an Arduino Nano-based Interface that allows you to retain your Steering Wheel stereo buttons with an Aftermarket Stereo.

Obviously this doesn't work on ALL cars or stereos, but watch the video... you might be surprised at how easy this can be.

▶ Arduino Nano (just pick an inexpensive clone from the search results, I use the ELEGOO ones):

▶ The infamous "Black Box" project box

▶ "T-Tap" wire connector assortment

▶ Adjustable mini Buck regulator

▶ Single-sided "perf board" PCB board assortment
