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 ...

Sunnyvale, Calif.&#8212Maxim touts its MAX16806 EEPROM-programmable driver, for high-brightness LEDs in automotive interior dome, map lighting, and courtesy light applications, as the first that does ...

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 ...

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 ...

Usually, an MCU is considered a digital device. By default, its output voltage level can be either high or low and nothing in between. With the requirement to create an LED brightness control, the ...

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.
