Hi, I'm trying to get the potentiometer seen at the top left of the photo to work, essentially as a dimmer. I've managed to upload the Arduino sketch, but it isn't working. Any help would be greatly appreciated!
NB: I have little-to-no electronics experience so my understanding of jargon is limited.

int potentLevel; int ledLevel;
//*************************CHECK*****************************

void loop() {
total= total - readings[index];
readings[index] = analogRead(inputPin); total= total + readings[index];
index = index + 1;
if (index >= numReadings)
index = 0;
potentAve = total / numReadings;
Serial.print("Average Potentiometer Readings: "); Serial.println(potentAve);
//*************************POTENT >> LED LOOP CODE*************************
ledLevel = map(potentAve, potentMin, potentMax, 0, 255); Serial.print("LED Level: "); Serial.println(ledLevel, DEC); analogWrite(led, ledLevel);

}
+1 about the base resistor.
void setup was also commented out
This might work.
I just corrected the many mistakes I saw. Might have missed one...

Needs a GATE resistor, sorry, my / fritzy misread.
I was halfway into fetal position when I noticed it.
Goes to show what a half decent schematic would do, I should give up trying to read fritzy when I'm tired.
