Write an Arduino sketch to perform the following, being sure to comment all codes to explain how the various pieces function and to explain any new commands: 1. When the code begins, hold the voltage at Vin = 0 V for 5 seconds to fully discharge the capacitor. This should be performed in setup(). • Repeatedly apply 5 V to the Vin output pin and hold it for a period of 10t, then apply 0 V and hold for 10t. • Read the input voltage Vin and the output voltage VC at time intervals of t/50. • Send these readings, separated by a tab, to the serial port at a baud rate of 115200 bps. o Leave the ADC readings as they are – there is no need to convert them to voltages at this point. o Verify that your program functions properly by examining the serial monitor output.

Design a class tictactoe that: holds the following information about the game: two-dimensional array (3 by 3), and winner. add additional variables as needed. includes the functions to perform the various operations on objects. for example, function to print the board, getting the move, checking if move is valid, determining if there is a winner after each move. add additional operations as needed. includes constructor(s). write the functions of the class, and write a program that uses the class. the program should declare an object of type tictactoe. the program will create the board and store it in the array. the program will allow two players to play the tic-tac-toe game. after every valid move update the array, check if there is a winner. if there is no winner and no tie, then print the board again to continue.
