Storage register is used to control the output lines of 74HC595. Whenever we apply a clock pulse to it two things happen: The bits in the Shift Register move one step to the left. SER (Serial Input) pin is used to feed data into the shift register a bit at a time. There are situations where you want to interface many peripherals together and keep the low system cost and reliable. This chip makes it a little slower to drive the LEDs (you can only change the LEDs about 500,000 times a second instead of 8,000,000 a second) but it's still really fast, way faster. This means that we pretty connect them together, so that instead of controlling 8 outputs, the cascaded shift registers can now control 16 outputs. Using the data and clock pin, we insert data into the shift register serially. The 74HCT595N on the Arduino Shield is used to drive 8 motor bridge pins (M1A, M1B, M2A, M2B, M3A, B3B, M4A and M4B).
