Here is a simple Arduino Camping Light project. In this design ... This part number (and ofcourse the LED type) is not very critical. If you want to use a bi-polar transistor, don’t forget to add a ...

Looking for a simple circuit to control the light intensity of Light Emitting ... we can use the low voltage output from the Arduino ports to control high voltage/current loads -the popular “12V LED ...

An Arduino drives the switch-mode power supply, offering dimming thanks to PWM, and the ability to automatically switch the light on and off using an RTC chip with a battery backup. The sketch ...

MIT’s Media Lab is working on a system of information-sharing that can use light-based communication to remind you of an appointment or program an Arduino. The coin-sized Droplet is an ambient ...

[Scott-28] recently sent in a particularly well-documented project that turned an antique rotary phone into a digital kitchen timer using an internal Arduino ... seven-segment LED display to ...

This Arduino-powered Shiftbrite LED ambilight setup takes things a step further by automatically adjusting the color and intensity of the ambient lights on the back of the display to match ...

Runner and Arduino enthusiast Nikodem Bartnik has created a DIY 100m sprint timer which is placed at the finish line and signals the start of timing via an audible bleep from its integrated speaker.
