I have what I hope is a simple question that I can't seem to
find an exact answer to. I am starting to learn electronics
and circuits, and have been playing with some microcontrollers.
Here is my question.Let's say I have an output off of one of the
pins of my microcontroller at Vcc which is 5 volts DC. I want to use
that output to connect to the coil of a relay. However, that requires
12VDC to activate the relay. It seems simple enough, but how
do I bump up the voltage from 5V to 12V ? I was looking
at the Wall PF5S12-84 IC, which seems to do this. However, am
I making this too complicated? Is there a better/simpler/smarter
way? Or perhaps it is as simple as a few common components
wired together to perfrom the magic.
thanks for any insight you may have!
