For our course project 1 DC geared motor is required.

T= Fr Load Torque in N-m (convert it into kg-cm)

V=68.550x10^-6

m=mass(64.437 x 10^-3)**

g= acceleration due to gravity (9.8)

F=mg (0.6443)

T= Load Torque in kg-cm (1.9331 approximately 2)

Rated RPM at 12V	Rated Torque in Kg-cm at 12V
1000	0.12
500	0.25
300	0.35
200	0.5
150	0.8
100	1.2
60	2
30	4
15	8
10	12
3.5	30

We will use DC motor of 60 RPM

Sl.no	Components	Quantities	Operating voltage	Operating current of each component	Total current
01	DC geared motors	1	12V	300mA	300×1= 300mA
02	Arduino mega 2560	1	5V	100mA	100×1=100mA
03	LED lighting	1	3.6V	30mA	30x1=30mA
04	IR sensor	1	5V	40mA	40x1= 40mA

12V	5V
300mA = 0.3A	170mA = 0.17A

We know Factor of safety = 3

12V	5V
0.3x3=0.9A	0.17x3=0.51A

THEREFORE, 5A ADAPTER CAN BE USED FOR 12V POWER SUPPLY AND 5A ADAPTER FOR 5V POWER SUPPLY
