I suggest putting together a starter kit. Then you expand one skill at a time by tackling projects.
First you need a work area / table. Must have some space, and be well lit. You’ll need space to store a bunch of junk too. (it just keeps growing)
A soldering iron and solder. I have a mungo sized variable power. But I started with a 40W radio shack pencil type. It’ll do everything you need, and is reasonably priced. Get a Multi-meter too. Stay away from the 10 dollar junk. This is the one item I’d recommend splurging on. Get what you can afford though.
Amazon has kits. Get a resistor kit, a capacitor kit and if you’re feeling it, a selection of wire. I recommend 22awg, both stranded and solid. (little spools are fine, stay budget concious until you know what you’ll use.)
You’re gonna need a power supply. Those can be kinda spendy. BUT>>>> you can build one out of an old PC power supply that will give you 3, 5, and 12 volts. It’s quite accurate and other than some connectors, pretty much free. PLUS it lets you tackle your first project.
If you wanna learn the coding side of it, I reccommend buying an Arduino. It’s a small microcrontoller with a lot of baked in features. It’s also super newbie friendly and well supported. Google “Arduino Projects” and your head will spin. Try to NOT buy a cloned Arduino. Sometimes they can be a little difficult to get thte drivers for.
Then someday, if you keep after it. You’ll have a mess like this.
