Concept

A serial-in parallel-out register: clock bits in, latch to pins.

CMOS 8-bit. Cascade Q7′ to next SER. Outputs source/sink a few mA — use transistors for heavy loads.

shiftOut() or SPI; latch pulse. ShiftPWM for many LEDs.

DIP-16 for breadboard lessons is ideal.

5 mm LED Assorted (R/Y/G/B/W)

LEDs & Indicators
