Having your windshield wipers transfer to the beat of your favourite track generally is a enjoyable second whereas driving, which is why YouTuber Cranktown Metropolis needed to make sure this may all the time be the case by including some intelligence to his truck’s wiper blades. The thought is easy: have a microcontroller “hear” to the music at present being performed, analyze the beat, after which transfer the wipers accordingly.

To start, the truck’s wiper blade management unit was ripped out and changed with an Arduino Uno together with a brand new DC motor driver and motor encoder for figuring out its absolute place. The Uno is ready to hearken to the music due to a tiny MSGEQ7 spectrum analyzer module, which takes the incoming analog music sign and splits it up into seven completely different bands of frequencies. When the common amplitude of the frequency that’s correlated with drums goes above a specified threshold, the place variable for the motor flips from 0 to 180 and vice versa.

After gluing every part collectively inside a watertight enclosure and attaching the machine to his truck, it was lastly time to take the system out for a take a look at drive. A lot to his shock and delight, Cranktown Metropolis’s “dancing wipers” mission labored fairly effectively and moved in sync to sturdy drumbeats. You may see extra about how he constructed this mission under!
