Current overflow

  • In interactive installation, mechanical parts and LEDs are always design students favourate choice in terms of electronics.
  • Most instructables online doesn't fit the use case scenario because they are always separate examples.
  • When a lot of moving parts are involved, multiple Servos/Power LEDs use the power exceeds Arduino's LDO which leads to insufficient power or damaging the board.

Possible solutions:

  • Use separate power source for Arduino and Power driving parts
    • Make sure that Arduino's Ground is connected with the driving circuits' Ground.
