I am fading....Oh...So help me..here guys, this are my sketches for my project..I upload the one that is broken for u guys to try it out...and maybe u guys can figure this thing out for me..
//Pin connected to ST_CP of 74HC595
int latch = 3; //14 green
//Pin connected to SH_CP of 74HC595
int clock = 2; //12 yellow
////Pin connected to DS of 74HC595
int data = 6; //11 blue
byte dataArrayRED[8];
void setup() //runs once
{
pinMode(data, OUTPUT);
pinMode(clock, OUTPUT);
pinMode(latch, OUTPUT);
Serial.begin(9600);
}
void loop() // run over and over again
{
digitalWrite(latch, HIGH);
delay(1000);
digitalWrite(latch, LOW);
delay(1000);
}
When I upload it, it doesn;t blink as I had hoped it would be, it just stays "on" without any fades or blink. Hm.....
The only part that lights up now, is that one part. Oh no~~ when I try uploaded some other programs that I've alter from the internet, it shows the same results. How could that be???
//Pin connected to ST_CP of 74HC595
int latchPin = 3;
//Pin connected to SH_CP of 74HC595
int clockPin = 2;
////Pin connected to DS of 74HC595
int dataPin = 6;
//holder for infromation you're going to pass to shifting function
byte data = 0;
void setup() {
//set pins to output because they are addressed in the main loop
pinMode(latchPin, OUTPUT);
}
void loop() {
//function that blinks all the LEDs
//gets passed the number of blinks and the pause time
blinkAll_2Bytes(1,500);
// light each pin one by one using a function A
for (int j = 0; j < 8; j++) {
//ground latchPin and hold low for as long as you are transmitting
digitalWrite(latchPin, 0);
//red LEDs
lightShiftPinA(7-j);
//green LEDs
lightShiftPinA(j);
//return the latch pin high to signal chip that it
//no longer needs to listen for information
digitalWrite(latchPin, 1);
delay(1000);
}
// light each pin one by one using a function A
for (int j = 0; j < 8; j++) {
//ground latchPin and hold low for as long as you are transmitting
digitalWrite(latchPin, 0);
//red LEDs
lightShiftPinB(j);
//green LEDs
lightShiftPinB(7-j);
//return the latch pin high to signal chip that it
//no longer needs to listen for information
digitalWrite(latchPin, 1);
delay(1000);
}
}
//This function uses bitwise math to move the pins up
void lightShiftPinA(int p) {
//defines a local variable
int pin;
//this is line uses a bitwise operator
//shifting a bit left using << is the same
//as multiplying the decimal number by two.
pin = 1<< p;
//move 'em out
shiftOut(dataPin, clockPin, pin);
}
//This function uses that fact that each bit in a byte
//is 2 times greater than the one before it to
//shift the bits higher
void lightShiftPinB(int p) {
//defines a local variable
int pin;
//start with the pin = 1 so that if 0 is passed to this
//function pin 0 will light.
pin = 1;
for (int x = 0; x < p; x++) {
pin = pin * 2;
}
//move 'em out
shiftOut(dataPin, clockPin, pin);
}
// the heart of the program
void shiftOut(int myDataPin, int myClockPin, byte myDataOut) {
// This shifts 8 bits out MSB first,
//on the rising edge of the clock,
//clock idles low
//internal function setup
int i=0;
int pinState;
pinMode(myClockPin, OUTPUT);
pinMode(myDataPin, OUTPUT);
//clear everything out just in case to
//prepare shift register for bit shifting
digitalWrite(myDataPin, 0);
digitalWrite(myClockPin, 0);
//for each bit in the byte myDataOut�
//NOTICE THAT WE ARE COUNTING DOWN in our for loop
//This means that 000001 or "1" will go through such
//that it will be pin Q0 that lights.
for (i=7; i>=0; i--) {
digitalWrite(myClockPin, 0);
//if the value passed to myDataOut and a bitmask result
// true then... so if we are at i=6 and our value is
// %11010100 it would the code compares it to %01000000
// and proceeds to set pinState to 1.
if ( myDataOut & (1<<i) ) {
pinState= 1;
}
else {
pinState= 0;
}
//Sets the pin to HIGH or LOW depending on pinState
digitalWrite(myDataPin, pinState);
//register shifts bits on upstroke of clock pin
digitalWrite(myClockPin, 1);
//zero the data pin after shift to prevent bleed through
digitalWrite(myDataPin, 0);
}
//stop shifting
digitalWrite(myClockPin, 0);
}
//blinks both registers based on the number of times you want to
//blink "n" and the pause between them "d"
//starts with a moment of darkness to make sure the first blink
//has its full visual effect.
void blinkAll_2Bytes(int n, int d) {
digitalWrite(latchPin, 0);
shiftOut(dataPin, clockPin, 0);
shiftOut(dataPin, clockPin, 0);
digitalWrite(latchPin, 1);
delay(200);
for (int x = 0; x < n; x++) {
digitalWrite(latchPin, 0);
shiftOut(dataPin, clockPin, 255);
shiftOut(dataPin, clockPin, 255);
digitalWrite(latchPin, 1);
delay(d);
digitalWrite(latchPin, 0);
shiftOut(dataPin, clockPin, 0);
shiftOut(dataPin, clockPin, 0);
digitalWrite(latchPin, 1);
delay(d);
}
}
Okay I give up. Maybe I'll try this after zohor prayer. Bye~~
