Hi..
i had this 12 inch led strip laying around so i decided to stick it at the back of my car and connect it with brake light wiring. So i did that and it was kind of boring to see turning on and off with the brake light. So i decide to PWM it. I simply used a uC and made a beautiful fading in and out(with 3 pattens since i had so much program memory left).
To keep things simple i connect the uC power and the switching transistor with the brake light + and -. Every time the brake paddle is pressed the uC boots and starts doing PWM and goes off when break is released. This on and off may happen 3 to 4 times per seconds depending on driving.
Will this turning on and off the uC kill it or reduce its life?
