Amplifiers (and voltmeters)
I am working on this project where I plan to make an wall mounted weather panel, ocean temperature, air quality, UV index, whatever meter! Essentially, a bunch of voltmeters connected to the output pins of a microprocessor.
If I understand correctly, the output of my microprocessor (the arduino) is 0-5v. Most voltmeters I can find are made for cars, and range from 8-18v. Is there a way that I can amplify the PWM signal coming out of my microprocessor from 0-5v to 0-18v? Or do you know of a better way to accomplish what I am doing? Maybe a supplier of 0-5v gauges? Thanks- -Jordan |
