Final Product:
Mechanical Components:
- 12x N52 Neodymium Magnets
- Plastic and Metal Gears (Spur & Bevel)
- Metal Shafts
- Couplers
- Bearings
Due to the limitations of the required gear ratios and the available sizes, plastic gears that were initially provided with the hub were replaced with either store bought/designed couplers to enhance steadiness and reliability of the gears latching onto the rod, reducing effects of gear slippage.

- 6x AAA batteries
- 4.7K Pull Up resistor
To power the Arduino Uno, we have decided to use AAA batteries as it is more common in households than the singular 9V counterparts. The voltage the Arduino required was ranging from 7v to 12v. Using 6 AAA batteries in a series circuit, we have reached the 9V required to power the Arduino which would then power the LCD and the Temperature Sensor.
