8.Battery Sizing - O-Division-2020-2021-Even/Repo-15 GitHub Wiki

SRno.	components	Quantity	Voltage Current drawn
1	DC motor	1	12v 300mA
2	SG90 servo motor	1	5v 1600mA
3	Arduino UNO R3	1	5v 100mA

For 12v Current drawn (C1)=300mA

For 5v Current drawn (C2)=1600+100 =1700mA

Now considering factor of safety FOS =1.3 C1=300*1.3

=390ma

=0.390A

C2=1700*1.3

=2210mA

=0.2210A

For time (t)=5hrs @12v

Battery required=0.390*5

        =1.95Ah

@5v

Battery required=0.2210*5 =1.105Ah
