I am attempting to build a PIC version of a brake light flasher. I build an Analog version, which works but was rather cumbersome (and boring), so i would like to apply what I am learning on the PICs.
My question (from not knowing a ton of electronics) is how can I switch a 30 watt load? Voltage would normally be 13.5 or so, giving about 2.22 amps?
There are two 15 watt bulbs, in parallel, which would be flashed.
Additionally, would turning them on/off be better than PWM? They are incandescent, not LED, if that matters.
My thought is turning them off to flash them would provide protection against PIC circuit failure?
I think i can figure out the delay sequence based on Nigels tutorials, but if anyone has sample assembly code built around this, I am open to any options. Analog version had adjustment for amount of time to flash, and number of flashes.
