so i have once again redesigned everything

AC:
i wanted to add an ac output. why you may ask idk its funny. anyways i add an inverter after the boost converter and another output and to read the voltage of the ac output i added a ZMPT101B and i plan on making a sorta oscilloscope to the ac output cause it cool

Display:
i switch to a bigger spi oled because it can be controlled by digital pins and i need the analog pins to read the new outputs
