Hello everyone ... after a few years looking for my answers ... using google, I am going here for little help.
I have something like "smart home" .... using Arduinos, Raspberry, Open Hab and so on ... and at this moment I need to listen to any advice on how to do follows ...
I've got few of lights circuits using LEDs ...
It is controlled by ARDUINO MEGA with PWM signal, with this little MOSFET board https://arduino-shop.cz/photos/produkty/d/1/1155.jpg?m=1550312675, but instead of IRF520, I am using IRL530N.
Dimming is working like a charm ... but my question is. I would like to dim more on the down limit ... so the LEDs will be able to have less brightness. I was trying to put resistors of different values and it worked, but also dramatically decreased the brightness of the LED at the full power...
so not sure how to do it ... if I need different Mosfet or different logic?
Thank you for any advice ...
