It looks super messy but what I have done is. I broke one trace and created the same configuration as in the correct schematic. I connected the resistors wrongly and that caused all the power to go to ground instead of dividing the voltage to the analog pin and the ground. It looks super messy but what I have done is.

Now that this works I can work on the final design of the board and send it to a board house. Now that this works I can work on the final design of the board and send it to a board house.

This is my final design that I am going to send to the board house. I don't need any bridge resistors because I can do 2 layers with vias.

I needed to submit my board 2 additional times because the first board was still faulty. The second board I forgot to export the solder masks and with the third one It got confirmed and accepted!
Something else I found out is that if you order 5 boards you get a big discount on the shipping so that saved about 10 dollars.
## Voltage divider ## Voltage divider
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 week I learned how voltage dividers worked and I also struggled a lot with them.
