The MAX7221 is a compact, serial input/output common-cathode display driver that interface microprocessors (µPs) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 ...

A common display found on digital watches and readouts that looks like a series of 8s. Each digit is formed by selective illumination of from one to seven separately addressable segments. For more ...

In a previous article, we explored the behavior of an LED diode as a small light source. We have seen how important a protection resistor is to light up this component. In this article, we will ...

The single-digit seven-segment BD Series LED displays are available in a range of six different digit heights from 0.276 (7 mm) to 1.0 in. (25.4 mm) in 24 different styles and models. Common anode or ...

Many options exist to drive seven-segment LED displays, but most are limited to low output currents. The approach described here uses one 74ALS374 or 74AS374 octal latch, wired as a shift register, ...
