Title: I’ve worked in technology my entire career but when I was replacing a broken wired garage door opener with arcade buttons I realized I had no clue what I was doing.<p>I couldn’t tell you the difference between wires or what was happening beyond randomly stripping wires and connecting them to see what happens.<p>My method worked for what I figured was a low voltage &#x2F; risk project , but I would like to know more and eventually be able wire a raspberry pi for hobby projects &#x2F; be able to manage more complex work.<p>Is there a good place to start &#x2F; has anyone started from nearly 0 and found some good resources?
