SHIFT REGISTER LED DISPLAY CODE (2)
COPY & PASTE CODE INTO ARDUINO SOFTWARE ENVIRONMENT
//....................................................SHIFT REGISTER 2 PROGRAM………………………………………..
//……copy and paste code into arduino ide a free software environment
//........that can be downloaded to use
//.. THE ATTINY85 WAS USED TO TEST THIS EFFECT AND USES PIN 0,1,2 AS DEFINED
//… .BELOW IN THE TOP OF THE CODE
//.........IT IS A SMALL SIZE AND CAN DRIVE THE SHIFT REGISTERS LIKE THE ATMEGA328PU
//.........IF THIS METHOD IS USED, IT FREES UP THE ATMEGA ON BOARD TO MAYBE DRIVE THE //….....DOT MATRIX DISPLAYS
//..USING THE ATMEGA ON BOARD SIMPLY CHANGE THE PINS FROM 0,1,2 DATA PIN,
//..LATCH PIN, CLOCK PIN TO 9,10,11 IN THE CODE OR USE STANDARD SPI PINS
//.10,11,13 ALL PINS AVAILABLE ON LEDLABS ATMEGA SECTION
//..spi pins , clock 13,11 data in, and 10, latch/strobe, .IF USING THESE SPI PINS
//..THESE ROUTINES CAN ALSO BE STROBED WITH SOUND,
//..DOWNLOAD THE CODE TO ATMEGA328P OR ATTINY85 OR PREFERRED MICRO AND TEST //.FUNCTIONALITY
//. DISCONNECT THE STROBE PIN GOING TO THE SHIFT REGISTERS AND CONNECT THE PWM //..FROM MIC BASS MODULE
//..ADJUST PWM FOR CORRECT AMBIENT SOUND LEVEL TO MAKE IT SOUND ACTIVATED
//..TRY ADDING THE LATCH OUT OF THE MONOSTABLE BY PWM AS INPUT HERE AND LATCH //.OUT OF THIS TO STROBE IN
//..SETTING FOR A SECOND OR SO, THIS KEEPS THE PROGRAM CODE RUNNING AT THE
//..SAIID INTERVALS, IT IS QUITE POSSIBLE THAT THE LATCH OUT OF THE MONOSTABLE //..WOULD REQUIRE INVERTING FIRST BY USING ONE OF THE HEX INVERTERS IN THE
//..SCHMITT TRIGGER SECTION, THEN CONNECTING TO THE STROBE IN OF THE SHIFT //..REGISTER.
//..IF THE PWM IS SET UP TO MATCH THE SOUND/MUSIC WELL THIS SHOULD NOT BE //../NECESSARY
//..THE INVERSION THROUGH THE HEX INVERTER MAY YIELD BETTER RESULTS.
//..ALTHOUGH THE MONOSTABLE LATCH OUT AFTER INVERSION FROM THE HEX INVERTER //...WITH A 1-2 SECOND DELAY
//..ALSO GIVES A GOOD EFFECT. IT IS A LOT LESS OF STOP START OF THE PROGRAM
//..AS A SECOND OR SO CAN BE VIEWED OF THE CODE (LED DISPLAY) WHEN TRIGGERED
//..THESE ARE JUST EXPERIMENTAL IDEAS, AND NO CODING IS WRITTEN INTO THE
//..PROGRAM TO MAKE IT SOUND ACTIVATED
//Define which pins will be used for the Shift Register
