This week Steven and I focused on getting the keypad to work with the microcontroller and LCD screen while still keeping the INA219 connected and working. We first tried to do it by connecting the wires for the keypad directly to the microcontroller. We quickly ran out of pins and realized that would not work. This was something we had planned for during the design stage. Having in front of us we played to see where our limitation were. We reverted to the notes for the resistor layout that would allow us to connect the keypad using one pin from the microcontroller.
