i am currently using an atmega8 to control my lcd.
i am using ic7805 voltage regulator to provide for its vcc.
i have shorted avcc to vcc. should i do the same for avcc as well... or does it need some other external reference?
the title says it all...
my question is simple... are there transistors easily available that can be configured to provide upto 3ampers in the saturation region? if yes, whch ones?
further information:-
the transistor is being used to control an electronic lock.the device switches between cut off and saturated region.
the collector is connected to a lock which is further connected to 12 volt dc.
when there is no current on base the transistor is in cut off- infinite...
