I read somewhere that it's a good idea to provide every chip with it's on cap, but I don't remember what would be a good general size or type for all chips.,
What if you had lots of chips and lots of caps? Would they loadup the regulator?. Would a 1 amp voltage reg freek out on startup?
I will be using two 555 timers , six 4066 cmos chips, three LM3914 led drivers, twenty plus leds and few other things. All consuming about 250 Milliamps.
I also read it's a good idea to use diodes to protect chips from reverse voltage.
Do I use them in series or back to front parrallel?
Which diode is suited for this job?
which pics below do I use?
(Only power side drawn)
Can I also use an NPN tranistor as a power switch ,instead of a relay ?
Do i really nead to use the caps and diodes , or is it a whole lot a bull-dust.
What if a cap or diode was to fail?, goodbye to a working circuit?
Thanks
