Example 4 - Dual Shift Register - KITT is back!
Just like the TV program, KITT made a re-appearance, but the new version had a dual sweep light on the front of the car. To achieve this, we need two arrays to store the left and right (Byte 1 + 2) values, and again an additional line to write out the second byte.
int dataPin = 2; //Define which pins will be used for the Shift Register control
int latchPin = 3;
int clockPin = 4;
int seq1[14] = {1,2,4,8,16,32,64,128,64,32,16,8,4,2}; //The array for storing the
// byte #1 value
int seq2[14] = {128,64,32,16,8,4,2,1,2,4,8,16,32,64}; //The array for storing the
// byte #2 value
Void setup()
{
pinMode(dataPin, OUTPUT); //Configure each IO Pin
pinMode(latchPin, OUTPUT);
pinMode(clockPin, OUTPUT);
}
void loop()
{
for (int x = 0; x < 14; x++) //Array Index
{
digitalWrite(latchPin, LOW); //Pull latch LOW to start sending data
shiftOut(dataPin, clockPin, MSBFIRST, seq1[x]); //Send the data byte 1
shiftOut(dataPin, clockPin, MSBFIRST, seq2[x]); //Send the data byte 2
digitalWrite(latchPin, HIGH); //Pull latch HIGH to stop sending data
delay(75);
