Overall our product require 3 main components:

1. Turn Table – Rotation of conveyor system

2. Coffee Grinder – Grinders coffee to a specific micron

3. Heat sealer – To close the drip bags

How is it controlled: 

1. Arduino

2. Stepper Motor

3. Gear movements

4. Hall Sensors

5. Slider

Flow Chart: 

Prototypes: 

This was when we used a DC motor instead of a slider to close the sealer

We realised that it would not work as the torque applied onto the sealer was uneven, resulting in uneven sealing of the bag. To ensure reliability of the bags we produce, we had to ideate and change up our strategy
