Copy the code below: void setup() {// put your setup code here, to run once:pinMode(11, OUTPUT);} void loop() {// put your main code here, to run repeatedly:analogWrite(11, 255);delay(1000);analogWrite(11, 120);delay(300);analogWrite(11, 80);delay(80);analogWrite(11, 200);delay(90);analogWrite(11, 255);delay(100);analogWrite(11, 95);delay(300);analogWrite(11, 160);delay(400);analogWrite(11, 255);delay(200);analogWrite(11, 150);delay(500);analogWrite(11, 124);delay(100);analogWrite(11, 195);delay(600);analogWrite(11, 255);delay(200);analogWrite(11, 42);delay(40);analogWrite(11, 76);delay(120);}

This siren is printed in 3 pieces: the motor mount, the chopper and the 2 port stator. Motor Size: 24mm Chopper Shaft Hole Size: 2.5mm Screw Hole Size: 2.5mm I made the chopper’s shaft hole slightly bigger than the 2mm motor shaft because at 2mm the shaft doesn’t fit correctly so I put glue in the hole and before attaching …

const int ledPin = 13; int brightness = 0; // Simulated brightness level (0–255) int fadeAmount = 5; // How much to change brightness each cycle void setup() { pinMode(ledPin, OUTPUT); } void loop() { // Simulate brightness by adjusting ON time digitalWrite(ledPin, HIGH); delay(brightness / 10); // ON duration scales with brightness digitalWrite(ledPin, LOW); delay((255 – brightness) / 10); …
