Circadian rhythm light bulbs can improve sleep by limiting the melatonin-suppressing blue light of regular LED bulbs. Some can automatically dim at night.

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 ...

In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

If you happen to be in the market for a small artificial sun, you may be interested to know that for about $1300, you can get a tennis-ball-sized LED array that outputs 120,000 lumens.

Great Cow BASIC (abbreviated as GCB or GCBasic) is an open source compiler that allows you to program PIC (Microchip) and AVR (Atmel/Microchip, including the ATMega328P in the Arduino Uno) ...

DimmingLight is a small library that allows you to adjust the brightness of a dimmable lamp with minimal code. It works with any lamp that supports PWM (pulse-width modulation) signals, such as LED or ...

The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...

TM1637 is a kind of LED (light-emitting diode display) drive controller special circuit with a keyboard scan interface. It is internally integrated with MCU digital interface, data latch, and LED high ...

Somewhere along the line, consumer display technology became an alphabet soup full of terms using the letters “LED.” In this succinct guide, we’ll provide a brief overview of common initialisms found ...

Controlling the light brightness or fan speed is often done using a regulator found in switchboards. But can you control them using a smartphone? Yes. Although it’s possible, there are hardly any IoT ...
