Shift registers are a popular method for adding extra outputs to microcontrollers.

The Shift Register Breakout board contains two 74HC595 shift register ICs, and allows you to control 16 outputs using only 3 pins on your microcontroller.

The shift register is arranged to fit easily on a breadboard with connections for VCC,GND and the three control lines on top.

Several shift register boards can be daisy-chained to add even more outputs.
