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.
