pcb reversing

Description:

Our undercover spy has successfully retrieved a mysterious PCB from a secret laboratory. We need your help to make the LED on the PCB glow. There are multiple switches, but only the ones labeled A, B, C, D, and E are relevant to this mission. Can you figure out a way to make the led glow?

In addition, the spy also recovered a damaged CD, but most of its contents were corrupted. Fortunately, our recovery team managed to salvage some key data that looks like design blueprints or schematics. We’ve attached the recovered data below, this might hold the clues you need to complete the puzzle.

Instructions:

1. Reset Procedure: After powering the PCB on, you must reset it to the starting position:

    - Press and release the E button once.
    - Then, press and release the D button.
2. Verification:

    - This challenge is manually verified. Once you successfully make the LED glow after resetting the PCB to its starting position, approach the onsite Traboda support team for verification.
