Thanks for the responses, I will try to respond to each one as well as I can. Would anyone be able to help with the final steps to a completed circuit? This one looked super close, however I wasn't sure the issue of the current set had been resolved What I want to do, however ended up with shiftPWM solution This one from 3 years ago, is what I want to do, however the thread stops before it's concluded I found some threads that were so close…. There's lots of talk about pull up, pull down, etc, however nothing really "final". Then read about some ways to use PNP transistors (I have lots of them) Then discover it's a current drain, so won't work as expected
#Arduino pwm fet how to
Then I hit upon the typical problem of how to add more PWM, as I need more than Arduino has. (It turns out that given I am using the same power source, and the ground is connected to V-, all I have to do is connect V- to the strip channel, and gnd/signal to Arduino, the other 3 terminal connections are not needed) With these, I could put my 5v power supply to a rail, take power to Arduino from this, power the LED strips directly from the source, and not worry about current through the Arduino pins. I got them on boards, with terminals for in and out power, and with various diodes and resistors built in, so some of those elements are taken care of, they are this model: IRF520 MOSFET Driver Module (HCMODU0083). Then, as I need more power, I read up, and settled on IR520 MOSFET. The functions however are limited, and I want to create my own, from an Arduino Micro.įirst up, I got three pwm of the arduino to control a normal RGB LED. I assume since they are strips, that the current limiting is built into the strip, (as opposed to the controller), and is therefore not necessarily an issue. I have LED strips that run off 5v USB and have the little remote to control them. I have seen this asked, and sort of answered, a number of times, and yet never quite seen a complete answer.
