I thought about trying something similar and tapping into the brake lights. The eye sockets are definitely big enough for some single, red LEDS.
I am thinking of making them Breathe with an Arduino Nano that does have
PWM (Pulse Width Modulation) pins. Mount it in a small waterproof box with
a Buck DC-DC power supply (12v - 5V) inside the tailgate. If it was to be done
with the brakes, there would be a trigger wire and extra code to be written.
This is the Arduino Code I found:
void setup ()
{
pinMode(3,OUTPUT);// declare pin 3 to be an output
}
void loop()
{
for (int a=0; a<=255;a++) //loop from 0 to 255,it controls the increase in PWM brightness
{
analogWrite(3,a); //set the brightness of pin 3:
delay(8); //wait for 8 ms
}
for (int a=255; a>=0;a--) //loop from 255 down to 0,it control PWM brightness reduction
{
analogWrite(3,a); // set the brightness of pin 3:
delay(8); //wait for 8 ms
}
delay(800); //wait for 800 ms
}
This is a Sinosodial wave code. I do like the Gaussian Fade better but,
I have only found the code for RGB Addressable LEDS so far.
