I want to start a project where I want to use the arduino for an inverter project, im fairly new to arduino's..... I was reading that the output frequency is fixed but I have seen where persons have made inverters using the arduino so I am assuming that there must be a way to change the frequency.
For example if I am to use 2 pins to output a pwm signal at 200hz can that be done?
See [u]Analog Write[/u] for the default PWM frequencies. And [u]Secrets Of Arduino PWM[/u] for a few different ways of changing it.
For example if I am to use 2 pins to output a pwm signal at 200hz
You only need / only can use one wire to do this.
Ok better question since I did some reading, I found out that I can use a arduino-pwm-frequency-library but I cannot seem to find one that works, based on what I read Im suppose to open the arduino ide, click sketch, include library and add the zip file (library I downloaded).
I keep getting Arduino: 1.6.13 Board: "Arduino/Genuino Uno"
Specified folder/zip file does not contain a valid library.
I found the link in the arduino forum and there is only 5 downloads available and I get the same message for each one.
can I get some assistance?
Hi, You don't need a library to change PWM frequencies. See THIS Page.
click sketch, include library and add the zip file (library I downloaded).
You are supposed to unzip it before you add it to the library and also sometimes it will have a " master " prefer to the name that also must be removed.
But as Terry says there is no need to use a library.
