Servo Motor Servo motors is a special type of motor which can not move 360 degrees, however, it can move 180 degrees. Furthermore, it can be used for making smart dustbin project, smart door lock and robotic arm. In this project, you will learn how to interface Servo motor with Arduino. Below servo moto pins

Example-1- Write the solution set of the equation x2+x-2=0. Solution- x2-x+2x-2=0 x(x-1)+ 2(x-1)=0 (x-1)(x+2)=0 x=1 , x= – 2 S={1, -2} Example-2- Write the set {x: x is a positive integer and x2<40} Solution- S={1, 2, 3, 4, 5, 6} 7, 8, 9, 10, ………… can not be included because their squares are greater than

In real life, we often come across collection of objects viz. #Cricket Team #Pack of Cards #Members of a Club In mathematics, we also come across collections, examples are. #Odd natural numbers #Even natural numbers #Numbers which is divisible by 3 and less than 20. If you observe each example is well-defined collection of objects.

Write a program which finds sum of natural numbers in Python. To understand sum of natural numbers in Python, first understand natural numbers. Set of natural numbers are denoted by N and it is positive whole numbers without having element zero i.e N={1, 2, 3, 4, 5, 6,………..}. In this program I will add first
