The sound sensor detects clapping or any loud sound, and sends a digital signal (HIGH) to the Arduino. Based on this signal: The Arduino turns ON the motor and LED. After a few seconds, the Arduino ...

Arduino Uno and official Arduino Ethernet shield. Should work with other Arduinos and compatible Ethernet shields. 2Gb micro SD card formatted FAT16. pins 5 to 9 as outputs (LEDs). TRIGGER_PIN 3 ...

[Kalle Hyvönen] just finished building his own aquarium lights. He used four powerful soft-white LEDs, mounting them on a pair of heat sinks to keep things cool. Now he could have just connected ...

This Arduino lights dimmer project is based on Doug Hitchcock’s comment: “I need to have a lamp dimmer that can “cascade” from one lamp to the next (up to 4 lamps). Basically, when you close a switch, ...

I had the idea of building this Arduino icicle lights project during the making of the light dimmer circuit and the result can be seen below. Is not a complicated project so it can be done easily by ...

Chirp announces the first official integration of data-over-sound on Arduino’s range of boards, allowing projects to send and receive data wirelessly.

The SoundDuino Arduino sound shield is capable of working with voltages from 3.3v to 5v and if you use the other Arduino boards, the only pins that you require are GND, VCC, RX, TX.

If you like decorating your house for the holidays, these digital LEDs save the trouble of manual teardowns by using Arduino to modify animation effec ...

Arduino controlled Christmas lights! It all started because [Anx2k] had some leftover LED’s from one of his other projects, so he decided to make use of them as permanently mounted Christmas lights.
