Controlling a toy car in a race track using an Arduino and a sonar
Published by António Lopes on July 19, 2013

I thought about creating different ways to control a toy car in a race track, instead of the typical handheld joystick-like device. One of those ideas was based on the use of a sonar (that measures distance to an object) as the controller for the car – the closer the hand to the sonar, the highest the acceleration.

However, considering that the sonar works through eco-location and that the track makes an infernal sound, the sonar accuracy is affected by the sound of the track, thus rendering this approach useless.

Any alternative ideas? I will try the best one (as long as it is not cost-prohibitive) 🙂
