This week I learned how voltage dividers worked and I also struggled a lot with them. A voltage divider is better for splitting voltage instead of creating a voltage drop using a single resistor. Because you don't have to know how much current is flowing. Instead you can divide the voltage between 2 lanes. This way you can receive an 5v analog signal on a esp without frying it.

I found a lot of helpfull explanation on [this website](https://www.khanacademy.org/science/electrical-engineering/ee-circuit-analysis-topic/ee-resistor-circuits/a/ee-voltage-divider).
