I am on a project in which I need to make bicycle dynamo frequency meter. The power generator’s output should vary with the speed of the wheel.
Which parts do I need to make it work?
The project should look like: : http://www.lanzo.se/experiments/dynamo/dynamo.html or http://practicalphysics.org/bicycle-dynamo-and-oscilloscope.html
-->without oscilloscope ( which is replaced with Arduino and panel )
