Shift registers can help reduce size and BOM in designs that use LEDs. By providing I/O expansion, they enable the use of smaller, less expensive microcontrollers. In some cases, the shift register ...

Sometimes you have to switch a light. Maybe it’s an LED but sometimes it’s mains-powered. That’s not too hard, a transistor and a relay should do it. If you have to switch more lights, that’s not too ...

This article discusses the solution of employing shift registers to reduce size and bill of materials in LED designs. In designs that use LEDs, shifter registers can be very useful. For instance, if ...
