I want to control the brightness of my LED strip. In this way, I'm thinking about using a MOSFET N-channel. Can you see what I conceive below :
I want to manage the Id current by shifting the Vg voltage thanks to PWM of Arduino. Can you see below my idea :
May I have your opinion about :
- Can I control Id current by shifting PWM on the pin D6 of Arduino MEGA (i.e by controlling Vg)?
- I have big trouble to understand MOSFET datasheet, could you help me and explain me which one could I use ?
Thank you for your help !
I have added an example of the Vg voltage which is a PWM applied on the GATE. Could someone says me if :
- Does voltage on the GATE of the MOFSET (here Vg) control the current flowing between the DRAIN and the SOURCE ?
- If yes, can I control the current flowing through the MOSFET by applying a PWM on the GATE of the MOSFET ?
