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 ...

The cathodes were bent perpendicularly and forms columns of 16 LED’s. This way, if power is applied to one row and a single column is grounded, one LED will light ... to use an Arduino to ...

It works like you’d probably expect — the light moves back and forth between the two players. Keep it in the green and you have a nice, gentle volley going. Let it hit your red LED and you ...

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 ...
