Abstract :
Dispenser is a household appliance that uses electricity to heat the heating
element and run the cooling machine. A dispenser uses a working principle with
heating elements and a cooling machine. Therefore, a smart dispenser is designed
that can remove water using voice commands using the Blutooth HC-05 module.
This control system utilizes bluetooth on Android smartphones. Bluetooth module
will be used to receive commands from users via Android to send string data to
Arduino. After testing 20 times, the success rate of 100% was obtained, because
the type of water desired was in accordance with the water output in the glass.
The maximum distance of using bluetooth module is 30 meters without obstacles
and 20 meters with obstacles.
