First you tell us what the output pulse voltage, frequency, and pulse-width are, also the bulb wattage or current.what do I do..?
I've IRF3205 mosfet...how do i connect it.You can use a MOSFET to control the bulb current.
Where can you buy parts?
Connect :-how do i connect it.
Wow...perfect...it worked just fine..thought the 555 cant operate on 12v..thanks..Connect :-
the FET gate to pin 3 of the 555,
the FET source to ground,
the bulb between the FET drain and the 12V supply.
Remove the 7805 regulator.
Drive pins 4 and 8 of the 555 directly with the 12V supply.
Its data sheet tells all.thought the 555 cant operate on 12v.
Yh...guess I misssed out..actually that was first stage..now i have my pulse signal able to light up the 12v bulb..the initial plan was having 2 12vbulb..bulb A flashes 5 times and stops b alsso flashes 5 times and stops then A and B flashes 5 times and stops..then it recycles if possible..i've got couples of relays and timers..i already generated pulse that can help make the bulb go on and off..Its data sheet tells all.
