Question: Could we just use the PWM feature of an Arduino to generate the 50% duty cycle we need for the Coqui or for a water conductivity meter?

Still working on a low cost conductivity sensor/data logger. Was writing code for my Arduino Uno the other day and got reminded of the PWM feature while looking at information on different pins. This article from NYU reminded me of donblair's post about 555 timers and duty cycles.

Anyone have any experience with this or thoughts on the feasibility?


I think it's possible, yeah! I'm not sure how fast PWM is or how easily you can set the rate?
