Free courses for beginners

Hello, I recently started learning arduino as new hobby as someone who has zero knowledge on programming or electronics and I’ve been really enjoying it and learning a lot. But the tutorials I’m following were made in 2019, and even tho they’re really good and are helping me understand the concept really well I find as I’m getting deeper into the course that a lot of the codes don’t really work the same as the original creator and I’m having to rely on ChatGPT to modify so they can work (which I don’t really like because I want to understand what I’m doing). And I wonder if it’s because they might be outdated now. What are the best tutorials to learn in 2026?

Voltage divider confusion

I just started learning arduino yesterday and I’ve been watching YouTube videos to learn the basic using wokwi since I don’t have the starter kit yet and everything was going smoothly until I started learning about the voltage divider. Can someone explain where is it used and how the code works. I tried recreating the circuit I saw in a YouTube video but I’m not getting the results as the creator and idk what I’m doing wrong. I keep getting 5v as if the resistors aren’t working. Should I skip over this concept for now?
