Simple Technique Drives Multiple LEDs From One Processor Pin
Driving multiple LEDs with one microprocessor GPIO pin is a well-known technique. Typically, designs perform this task by issuing pulse widths and clocks of differing durations and employing multiple RC networks to distinguish between them. The design described here is much simpler. The microprocessor pin is connected to the clock of a multipleoutput sequential counter (see the figure). In its...
