Redstone in Minecraft is basically electrical engineering for people who don't actually want to study electrical engineering
You throw down some dust, place a repeater, connect a piston, and suddenly you have a door that opens when you step on it. That's the easy part. The hard part is figuring out how to make anything more complex than a flickering lamp without taking apart your entire build three times because you forgot which side of the repeater faces the signal. I've spent way too many evenings staring at a wall of cobblestone wondering why my sorting system isn't sorting anything at all. The short answer is YouTube and the Minecraft Wiki. Not in that order for everyone, but honestly that's the combination that works. Llmnael's videos are probably the most useful single resource if you're starting from zero. He doesn't hand-hold, but he shows you actual working contraptions at normal speed so you can see the timing. The wiki has every redstone interaction documented, though reading it cover to cover will put you to sleep faster than any textbook ever could. There are also subreddit threads on r/MinecraftRedstone where people post their builds and debug each other's problems. It's surprisingly active. I learned about block tick delays from a thread there that was three years old and nobody else had mentioned.
The practical stuff nobody tells you upfront
Redstone dust transmits a signal strength of 15, but it drops by one every fifteen blocks or every time it turns a corner. That's why you need repeaters. A repeater locks the signal strength at whatever level it receives and holds it steady. Think of it less like a wire and more like a copy machine. You can also use comparators, which are a different tool entirely. They read the content of containers or the signal strength of another redstone line. Most beginners use them wrong because they don't realize the difference between comparing a signal and just amplifying it. Pistons are the other thing people mess up. A sticky piston pulls blocks back when it retracts, a regular piston only pushes. But both have a one-tick delay between receiving power and moving. If you're building something that needs to happen in a precise sequence, you're working in increments of game ticks and the game runs at twenty ticks per second. That means you have about fifty milliseconds to think before the next thing happens. This is not human-scale timing. I ran into a problem a while back where my mob grinder kept clogging because the water flow was pushing mobs into a one-block gap I hadn't accounted for. The design I'd copied from a video assumed a flat surface, but my arena had a slight slope from where I'd placed lava blocks for the kill chamber. The workaround was to lay down slabs along the entire water path so the top surface was completely level. Took ten minutes to fix something I'd been debugging for two hours.
What actually makes redstone click
It's not about memorizing recipes. It's about understanding the basic components well enough that you can combine them without thinking. Once you internalize that a redstone torch is an inverter, that a repeater is a delayed buffer, and that a comparator is a directional signal reader, you stop trying to recall every circuit and start building from first principles. The counter-intuitive part is that simpler circuits are often harder to build. A two-by-two piston door is genuinely more difficult to get right than a thirty-block-long automatic farm because the door has multiple moving parts interacting simultaneously. The farm is just repeating the same mechanism over and over. Parallel repetition is easier than tight integration. Another thing that trips people up: redstone signals can pass through transparent blocks like glass or stairs, but the dust itself must be placed on solid blocks or on other redstone components. You can't just float dust in the air. This seems obvious until you're trying to run a signal under a staircase and you've placed the dust on a stair block half-slave and wonder why nothing's happening.

Resources that actually help
Llmnael on YouTube covers everything from basic doors to full-scale item sorting systems. His Redstone University playlist is structured but not condescending. If you watch him build something, pause the video before he places the final block and try it yourself first. That's where the learning actually happens. The Minecraft Wiki redstone page is dense but accurate. It has timing diagrams and signal strength tables that you'll reference more than you'll read through in one sitting. Keep it open in a second tab while you build. For people who learn by taking things apart, there's a community around redstone schematics and .mcfunction files for command blocks. These let you load pre-built machines into a world and explore them. It's useful but it can also become a crutch if you only ever copy without understanding. I caught myself doing this for about six months before I realized I couldn't build anything from scratch anymore. Had to step back and do some simple exercises again.
When redstone isn't the right answer
This isn't the place to hide, but it's true: for a lot of applications, command blocks or mods like Create do what redstone does faster and with fewer bugs. Redstone is limited by game mechanics. It can't do floating point math. It can't store large amounts of data efficiently. A 64K RAM unit takes up an entire room and runs at maybe one operation per second. If you're building something that needs actual computation, you're fighting the engine the whole time. Also, redstone contraptions break when chunk unload mechanics change. I had a working automated wheat farm once that stopped responding correctly after a minor update changed how block ticks were processed across chunk borders. It still worked in some regions and not others, which made debugging a nightmare. This is worth knowing if you're planning to share your build with other players on a server.
How to actually learn it
Start small. Build a repeater circuit, a piston door, a simple sorter. Then build a bad version of each and fix it. The fixing is where you learn. Copying a tutorial verbatim teaches you nothing about why it works. Take a tutorial you understand and change one variable. See what breaks. That breakdown tells you more than any guide ever could. I keep a spare world I call the redstone lab where I test everything without worrying about messing up my main build. It's saved me dozens of hours. You can do the same thing just by creating a new creative world and throwing blocks around. No pressure, no consequences. There's also a book called "Redstone Design Techniques" by a user named Kazzymodus that's been around for years. It's not updated for the latest version but the core concepts haven't changed. The section on clocks and oscillators is still the clearest explanation I've found anywhere.
