Draw State Diagram, Hardware Schematicsand write Arduino code for the following problemin TinkerCAD A vending machine has to be designed that contains 4 push buttons, 3 LEDs, 4 DCmotors. One push button is to be used for inserting the coins, and the remainingthree push buttons are to be used for selecting the item to be dropped whensufficient coins are inserted. Similarly, the first LED shows whether the vendingmachine is in locked state or unlocked state, the second LED shows when thereare insufficient coins to purchase any item, and the third LED indicates whetherthe item is ready to be collected when the item has been selected. Moreover, thefirst 3 motors are to be used to drop the three items, respectively, whereas thefourth motor is to unlock the door for selected item collection. The transition between each states takes around three seconds delay, and oncethe item is collected, the vending machine goes back to the idle state. You arefree to choose the price of each item. But once the coin is inserted into thevending machine, the currently inserted coin amount is to be displayed on theLCD display
