How do I create a speaker that gets louder the faster someone pedals on an electric bike? Answered
For a school project I am building an electric bike and thought it would be fun and an attention grabber if when people were on the stationary electric bike the faster they pedaled the louder a speaker would get. Is that even a possibility? The motor is an 1000 Watt motor on the rear wheel. I think that the higher the voltage or current, the louder a small speaker would get.
