/diy/ - Do It Yourself

how do i operate a relay using a microcontroller? i'm a midwit who can kind of understand how the relay works but not intelligent enough to understand what to use to switch the relay. i want to make an h-bridge. i am thinking of doing picrel. but i don't know anything about transistors and diodes and resistors.
which ones should i use? mcu pins put out 3.3v

i am trying. i really want to get into autosar programming, and automotive software development (even though i absoultely despise anything more modern than the Ford Sync 1 system, no one needs that bullshit, but i suppose it must be fun to work on.)
