The traditional way to control the output of multiple LEDs is to dedicate a pulse width modulation (PWM) controller to each LED and use the controller to transform the input voltage to a current that ...

Numbers are hard enough in English, but [Sadale] decided to take things a step further by building a calculator that works in Toki Pona. The result is Ilo Nanpa, an awesome hardware calculator that ...

The PCA9685 is an I²C-bus controlled 16-channel LED controller optimized for LCD Red/Green/Blue/Amber (RGBA) color backlighting applications. Each LED output has its own 12-bit resolution (4096 steps) ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...

A buck-boost controller IC with four external switching MOSFETs can operate from input voltages above, below, or equal to the output voltage, enabling them to regulate the light output for a string of ...

Merging multiple microprocessors with high-speed optical networks has been considered a promising strategy for the improvement of overall computation power. However, the loss of the optical ...
