Here’s an example on multiplexing three seven-segment LED displays from an Arduino using a single 4511 IC and a handful of transistors. This builds on my last post about interfacing to a single display

It appears that there are many different ways to interface a seven segment LED display to the Arduino; the humble 4511, 74HC595 shift register and a multitude of fancy (and expensive) serial ICs such as the MAX7219.
I decided to use a 4511 driver IC for this purpose as it was the only suitable chip I had lying around. It saves a few pins over driving the display directly from the Arduino and also works from a wider voltage range so can be used for driving large display modules.
