7.2 Power calculation
| 5V | Quantity | Current | Total Current |
|---|---|---|---|
| Arduino nano | 1 | 400mA | 400mA X FOS=400mA X 1.5=0.6A |
| Touch sensor | 1 | 20mA | 20mA X FOS=20mA X 1.5=0.03A |
Total current=0.6+0.03=0.63A
Power=VI
=5 X 0.63
=3.15W
Power calculation of Servo motor
Number of servo motors required = 1
Operating Voltage = 5 V
Current = 650mA
Hence, we have decided to use 5V 1A Adapter for Arduino Nano and Touch sensor
Embodied Energy Calculation
| Consumables | Dimensions | Quantity | Total Weight(kg) | Unit Embodied Energy (MJ/kg) | Total Embodied Energy(MJ) |
|---|---|---|---|---|---|
| Acrylic Sheet | Length = 17.5cm, width = 11.5cm, thickness = 4mm | 2 | 0.127 | 80 | 10.16 |
| Acrylic Sheet | Length = 6.15cm, width = 0.75cm, thickness = 2mm | 7 | 0.045 | 80 | 3.6 |
| Nut and Bolts | 2.5 inches x 3mm | 4 x 12 | 0.050 | 24.4 | 1.22 |
| Nut and Bolts | 2cm x 2mm | 8 x 12 | 0.030 | 24.4 | 0.732 |
| 15.712 |
