// Copy the following code into your active project file
// The first chunk of code (numbers 3 and 4) goes just BEFORE your void setup()definition.  
// The rest goes INSIDE your void setup() definition at the end of your initialization code.

// (Worksheet 4.6.1s Number 3)
// Create a function called clearRowPins() which uses a for() loop to turn OFF all eight of the LED row pins
// Use the functions you've already created to set and clear individual row pins
void clearRowPins(void) {

// Create another function called setRowPins() which uses a for() loop to turn ON all eight of the LED row pins
// It will look very similar to the clearRowPins function.
//


  // The rest of this code should go inside your setup() function after the initialization code
  // It will replace code that you may already have to turn individual lights on and off.
  //
  // (Worksheet 4.6.1s Number 5)
  // In the setup() function after all the initialization code create a for loop that turns on each color
  // (red, green and blue or 0, 1, 2) in turn and then waits 1 second ( delay(1000); )  
  // Before the for loop call setRowPins(); after it call clearRowPins().
  //

  // The outermost loop should cycle through each of the eight row pins in turn, 
  //    turning on that row at the beginning, and turning it off at the end.  
  // The next inner loop (between the on and off commands) should count to 128.  
  // The inner most loop should cycle between the three colors setting each and then
  //    waiting for a short time (1 or 2 mSec)
