A staple of consumer devices for decades, seven segment displays are arguably one of the most recognizable electronic components out there. So it’s probably no surprise they’re cheap and easy to ...

Seven-segment displays are needed in many instrument designs. In conventional microcontroller-based designs, four output port lines are allocated for one seven-segment display. Figure 1 shows the ...

The latest Super Blue single-/dual-digit, 7-segment and dot-matrix displays offer enhanced color, continuously uniform brightness, and high reliability for critical control applications. The BHS ...

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 ...

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 ...
