A classical design for directlydriving eight seven-segment LEDdisplays requires as many as 15 I/O lines.Previous Design Ideas have describedmany approaches for using a maximumnumber of LEDs with a ...

Interfacing microprocessors to LEDs or LED displays via a 2-wire, I2C-compatible serial interface, the MAX6958/6959 common-cathode LED display drivers are said to be the first such devices to offer ...

This seven segment art display makes use of a 81 seven segment red common cathode LED displays. The LEDs are arranged onto 100x100mm boards that each contain an Arduino Nano and 9 seven segment ...

The circuit was designed to implement the concept of Sam Gordon in making a digital clock with visible components from the viewer of the clock. The main clock circuit consists of TTL and several CMOS ...
