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. Now that this works I can work on the final design of the board and send it to a board house. +![alt text](image-16.png) +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. + +![alt text](image-17.png) +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 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.
