You are going to create an Arduino sketch where you have two push buttons, one piezo, one photoresistor sensor and two LEDs: Red and Green.

When the sketch starts, the Serial Monitor displays "Enter a number: ".

 If the number entered is 1, the red LED should turn on and the piezo will play a sound
only one time for 400ms.
 If the number entered is 2, the red LED should turn off
 If the number entered is greater than 3 the LEDs should blink only one time.
 The first push button should turn on the LEDs.
 The first push button should turn off the LEDs.
 If the value of the photoresistor is not between 400 and 700 the LEDs should blink.
 The sketch should print the value entered by the user and the value of the
photoresistor.
