Shift Registers

Read from and write to shift registers connected to Arduino® hardware

Shift registers are used to add additional inputs or outputs to an Arduino board. You can use the serial-in/parallel-out shift registers to control multiple outputs, or the parallel-in/serial-out shift registers to gather multiple inputs using one pin on an Arduino board. For example, you can control multiple LED lights using a single pin on an Arduino board. You can use the shift register functions to read or write serial data. The following shift registers are supported:

Create an Arduino object using arduino before you use shift register functions. See Connect to Arduino Hardware for more information.
