Testing Circuit Board CONNECTIONS and voltage levels

Design considerations for future versions

  • The barrel jack polarity should be reversed to follow the the centre-positive convention (not centre negative).
  • The ultrasonic sensor could be placed underneath the board to save space.
  • If I choose to create a case, a wider perimeter should be left around the PCB.

Reversing the polarity of the 9V to barrel jack adapter to work with barrel jack's centre-negative polarity.
