In arduino language!!

Write a program to display n terms of natural number and their sum. For any other given character, the program should return sum of 0. The program should start by asking the user to input value of terms. For example: "Please input value of terms" i.e. If the input value of terms is 7 The first natural number is 1 2 34567 The Sum is : 28 Hint: Use a for loop for the sum and a while loop to wait until the input buffer receives a character as a user input. Read about the parselnt0 function. This function will make your life much easier as it returns the first valid (long) integer number from the serial buffer. Characters that are not integers (or the minus sign) are skipped
