Is there anything majorly wrong with the below schematic? I'm still learning and I have followed the datasheet but feel like I'm missing something.

Revised Schematic with changes recommended and addition of A3400 fets

For anyone that finds this and has similar questions:

  • Remember pull-up resistor on buttons;
  • ULN2003: 150 mA limit per channel; better to use a FET such as AO3400.

    > Remember pull-up resistor on buttons; The ESP has internal pull-up resistors you can enable on it's GPIO. You can skip them if you want. – Connor Wolf Feb 17 '22 at 09:08
