This repository contains multiple Arduino .ino files with prebuilt animations and functions for a 10x10 LED Matrix Clock (Matrixuhr / Digitaluhr). The project is designed for a 10 × 10 LED field that ...

Today we are going to create a strobe light for the tips of the wings of an rc airplane using a 555 timer (NE 555 or lm 555 IC) this circuit is very easy to make with few components and most ...

There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the ...

If you’ve been to a wedding or a downtown coffee shop in the last 10 years, you’ve probably seen those little lightboxes that are so popular these days. They consist of letters placed on a plastic ...

Blue light is a high-energy part of visible light from the sun, screens, and light-emitting diode (LED) bulbs. Your cornea and lens don’t block blue light the way they block ultraviolet (UV) rays.

Abstract: A 9-bit sweep driver is proposed, enabling 240 Hz frame rate of a 4.5-inch active-matrix Micro-LED display with 160 × 90 resolution via analog pulse-width modulation (APWM). This sweep ...
