Description
I made a little test with some components to find out how to control the brightness of this leds strip, I couldn't find a good answer on Google so I came up with a solution.
Keep in mind that I am not an electronic so this solution could be not the best one, it worked and tested.
Items
- Leds strip
- Arduino
- N-Channel MOSFET, my was 2N7000
- 200 ohm resistor
Schema
Code
void setup() {
pinMode(5,OUTPUT);pinMode(6,OUTPUT);
}
void loop() {
analogWrite(5,0);
for (int i = 0;i < 260;i++) {
analogWrite(6,i);
delay(10);
}
}

Why do you put a resistor? And why 200ohm? How do you calculate that?
Thank you
I have followed ada fruit tutorial and what I understood is that the resistor is a security to don't burn the Arduino in case of overloading.
You can put something like 50-300
It would be helpful for you to label the FET terminals in your schematic. Gate, Source, Drain.
