##MOTOR SIZING OF STEPPER MOTOR Torque = F * r (In N-m) (SI UNIT) where F- Force acting on the body r- Lever arm length T- Torque

Volume=V=2.5x10^-7 m^3 (IN SI UNIT)

m=mass=(29.86*10^-3 )kg (IN SI UNIT)

g= acceleration due to gravity (9.81 m/s^2)

F=mg= (0.293)N (AS PER NEWTON'S SECOND LAW OF MOTION)

Factor of safety = 1.5

T= 0.5071 Kg- m

HENCE WE REQUIRE 28BYJ-48 Stepper Motor

SL No	component	quantity	operating voltage	operating current of each component	Total current
1	28BYJ-48 Stepper Motor	4	5v	270mA	1A
2	Arduino mega 2560	1	5v	100mA	100mA

Total current consumption=1A

Factor of safety=1.5

Total current consumption ( with factor of safety )=1A

Therefore we require an adapter of 5v,1A specification
