Image 6 : Power supply 12v
The 12V power supply is dedicated
to powering the motor dynamo
power window and the relay. This
voltage level provides the
necessary power to activate and
operate the motor efficiently. It
ensures stable performance and
prevents voltage drops, which could
disrupt the composting process.

The charcoal is used to filter any
potent and disgusting smell from the
organic waste that will turn into
compost.
