Circuit designed to work with ATtiny85Push a tactile switch to cycle through several different patterns on the LED strips. I want to modify the Arduino code so that I can use the ATtiny85 instead. *****The code posted here works on the Arduino Uno with a 10k pull-up resistor wired to the push button at pin 11 on the Arduino.

Try replacing the lines

#define DATA_1 (PORTC |= 0X01) // DATA 1 // for UNO
#define DATA_0 (PORTC &= 0XFE) // DATA 0 // for UNO
#define STRIP_PINOUT (DDRC=0xFF) // for UNO
int buttonPin = 11; //button pin variable, 11 on the Arduino

with

#define DATA_1 (PORTB |= 0X01) // DATA 1 // on PB0
#define DATA_0 (PORTB &= 0XFE) // DATA 0 // on PB0
#define STRIP_PINOUT (DDRB=0x01) // PB0 as output
int buttonPin = 3; //button pin variable, pin 3 = PB3

Connect the push button between PB3 and GND, with an external pullup. Connect PB0 to the data input of the LED strip.

If the program doesn't fit in the flash, try removing one of the largest patterns. Otherwise, if it almost fits, you could try to optimize it to make it smaller.

Edit: I modified the original code and added some optimizations. Notably, I removed all dependencies to the Arduino core, which makes it significantly smaller. Now it fits in the flash memory of the ATtiny85 without removing any pattern.

This is a polyglot: it should compile either as a .ino sketch, as a plain C program, or as a C++ program.
