STD Hotwheels Bento 1

Mode: Editors' pick
Simple board to control hotwheels car via bluetooth using an attiny84 and a dual motor driver.
You can use this board with one brushed motor on throttle and another brushed motor with a linear pontentiometer as a servo to steering.
Also, if you want to use "tank-mode" (where each motor controls a track), you can ommit the linear potentiometer input and control both motors directly.
