I can read the circuit diagram, but the actual wiring is blank and I don't know where to start.

Before you learn to climb, you should learn to run. If you want to learn well, the first thing is to connect a simple experimental circuit. For example, everyone knows what a short circuit is in theory, but you don't know it in practice. When voltmeter and ammeter are used, one is connected in parallel and the other in series. This is known in theory, but people who don't do it in practice still don't know how to use it. The wiring of relay contactor control system is usually loaded. If you want to connect the lines smoothly, you must have this picture in your mind instead of watching it connect the lines, so it is easy to miss a line. In short, it is usually practiced from a simple loop, and then it can be done well. No one can reach the sky in one step.
