CAMBRIDGE, UK — NEC Electronics announces the 78K0/Ix2 LED microcontroller demonstration kit, enabling efficient and intelligent LED driver design without any additional driver ICs but the company's ...

The LM3914 LED bar graph driver was an amazing chip back in the day. Along with the LM3915, its logarithmic cousin, these chips gave a modern look to projects, allowing dancing LEDs to stand in for a ...

Recently, I wanted to build a Sleepy-LED Eye as an add-on indicator for a small personal project. My idea is a near-replica of the iconic breathing pattern used for the “sleep” indicator in Apple ...

The algorithm in this microcontroller design this design drives an LED matrix and provides digital-voltage-readout and bar-like dot displays, showing dots for a graphical output if the input value is ...

This project is a wonderful example of what can be accomplished with a rather complicated logic circuit. It’s an Etch-a-Sketch made from a 16×16 LED grid. That in itself is only somewhat interesting.
