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 ...

The EM32-4-LED 4-digit LED display, targeted for use in microcontroller-based applications, provides a display area consisting of four, 7-segment LEDs and three decimal places. Each segment is ...

The 7-segment display certainly is a popular build, and surprisingly people still come up with new takes on this over a hundred-year-old way to represent numbers. This time ...
