Hello, im tring to design a lighting system for my bicycle...
Im tring to use a joule thief circuit tuned at 12-16VDC, so that i have a high frequency going to these 20Watt LEDs. im going to have a brake light, 4 Turning signal LED (2 front & back) and a head light. I want to use the joule
thief becuase of its fast pulse, and hoping that the current use is low. but if thats not the case, I want to find a microcontroller capable of driving these LEDs, via a pulse in the 120Hz+ Range. Here's what it should do:
Get on my bike, and start to pedal, a switch gets tripped on every rotation, telling the microcontroller to turn on.
Now we have front light, and rear lights on.
Rear light will need to be at like 25% to %50 of full brightness (Software Variable), until the brakes are hit.
Blinkers need to have a variable ON/Off time.
and last: Switch for high/low-Beams on front light.
so... any sugestions on what microcontroller to use?
Thanks
