 The main function of the button is to change the direction of the counting of the LED lights. In vcc1, like vcc0, you program the LED lights to count up to a certain number. In the vcc1, the LED lights count up to 64, and by pressing the button, the LED lights will count backwards from 63.
 =====PROGRAM=====
+The sample program in the project grabit will have the basic necessities to start off your program.
+First step will be to change the definition (pin #) of your button.
+Replace "num" with the wiringpi pin number of the GPIO for your button
+  #define BUTTON num
+Now we have to set the number of LED's that we are connecting to our Pi to specify the size of our pin array.
+Enter the number of LED's you are using, in the case of this project 6
+  #define NUM_LEDS 6
+Next, we define our variables. The sample program already defines both our index int value as well as declaring our pin array for pin assignments. If you would like to define a different variable for your counter or for any other necessary variables, do it here.
+<blockquote>Int container = 0;
+num_container = 32;
+</blockquote>
+Now we have to set up our pin array. Much like the last project, you're assigning each pin an array assignment (0-6) within the array, then defining what Wiringpi pin it corresponds to. Remember to set your pin for your button as an input and your led pins as outputs.
+Using
+  gpio readall
+in your terminal can help you find both the BCM number and the corresponding wiringpi numbers.
