i'm making a simple after burner effect for rc plane motorized with electric ducted fan (EDF) with arduino and leds strip

Project description

I build radio-controlled planes and for certain the engine is an electric turbine, the problem is that on real-size planes with turbine there are flames coming out of the reactor and not on my planes.

I therefore thought of making a system which imitates the flames at the exit of EDF with leds and an arduino.

To be more realistic the light intensity and or the color must change in function of the throttle.

It is necessary to connect the ESC and the arduino to the receiver with a Y, it is the ESC which supplies the power supply of the arduino and the leds, it is necessary to take care to respect the polarities.

At start-up the blue leds are on at 100% and decrease to about a third of the throttle then the lighting of the red leds increases to 100%

Here is the result in video (the in-flight video will follow when the weather is better)

Code

int changethrottle;
int voltageledrouge;
int voltageledbleue;


void   setup() {
  pinMode(5, INPUT); 
  pinMode(3, OUTPUT); 
  pinMode(4, OUTPUT);
   Serial.begin(9600);
}

void loop() {
  changethrottle = pulseIn(5,   HIGH, 25000); 
  voltageledrouge=map(changethrottle, 1000, 2000, 0, 255);
   voltageledbleue=map(changethrottle, 2000, 1000, 0,255);
  if (changethrottle<1250)   voltageledrouge=0; 
  if (changethrottle>1500)  voltageledbleue=0;
  analogWrite(3,voltageledrouge);
   analogWrite(4,voltageledbleue);
  
   delay(10);
  
  }
