AVR Projects with ATTiny 8-pin devices
AVR's ATTiny Series are packaged in a space saving 8-pin case and can easily
be programmed via their ISP interface.
Here are some programs to cover some small tasks , all built with AVR
Studio 4 (32-bit).

No color LEDS were used in that project. The LEDs are simply white.
The LEDs are connected with the anode to the outputs of the 4015 and all cathodes is grounded.
This is comparable to the common use of shift registers linke the widely used 74HC595. The 4015 contains two 4-bit Shiftregisters. They are cascaded like in the following link and a second 4015 follows to form a 16 bit shift register.
