List, cost of required Materials , Tools needed and plans for testing

We have been told to watch out for cost when considering our design and TEAM 'NOVA took that into consideration.

LIST OF REQUIRED MATERIALS FOR PROTOTYPE

• Wood
• Adhesive 
• Plastic ball
• Plastic materials 
• Big plastic bucket
• 9V battery
• An Arduino board(optional, we could have used a simple circuit completion to trigger the buzzer but we +chose to go with a micro-controller for prototype  because it is convenient and fits into our design , and also because we had a free one to use)
• Black paint for coating
• LEDs
• Bolt and Nuts
• 8 ohm speaker or buzzer
• Electrical Wires
• Resistors
• PCB or breadboard

TOOLS NEEDED

• Saw
• Nails
• Woodwork Hand tools
• Soldering Iron
• Spanners
• Drill

BUDGET BREAKDOWN

       Total = #2950 

PLANS FOR TESTING

Testing can easily be carried out. We just need some quantity of water and a bucket simulating the tank
