Hi.
I am a noobie at programming but I have a good degree and am blessed with an high IQ.
What is required is to pulse an LED Third Brake Light
How its works ?
Its pretty simple. As soon as you hit the brakes Third Brake light will flash at 20Hz.
And after 3 seconds Third Brake light will be Steady on.
Why Pulsing Third Brake Light ?
Because This will help get the attention of the drivers following behind you.
Even when your in bumper to bumper traffic.
Caution:
DO NOT CONNECT THIS CIRCUIT TO YOUR MAIN BRAKE LIGHTS. Any type of flashing light on the main brake lights is prohibited and illegal. Use this circuit at your own risk and be aware that the possibility exists to be stopped by law enforcement if you implement this circuit in your vehicle.
I have produced Pulse Train Graphs if anyone wants a better understanding.
But my question is this. What processor would be best for the job. I though that I could use a PIC but have been told that the ARM is faster.
this reminds me of some of the trash the mega terrorist and collaborator Pervez Musharraf/Busharaff wrote about himself. You don't happen to be him, I presume? Did you pay for your degree?
"...I have a good degree..."
What does that mean exactly? If you're trying to stand, 90 is a good value but if you're trying to sleep 0 is a better value.
"...an high IQ."
Well I've also got a high IQ ... If the score is compared to that of a horse.
I though that I could use a PIC but have been told that the ARM is faster.
What speed your looking for 20Hz. I belive speed of Frequency remains same 1/f.
why have been told Please calculate speed of controller and decide your self base on application.
Looking towards your solution seems to me timer is sufficient as andrew suggested...
