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 ...

If you have an unsupported Arduino, you can add its board support file or URL by clicking the small icon ... light. These traffic light boards usually have three or four pins: one for each colored ...

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 ...

Solder the battery pack to the Arduino. An Arduino is ... so I ordered the 50-light string. I’d recommend getting a single strand of 50 LED lights, but if you decide to get two sets, buying ...

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 ...
