From the minds at http://arduinotronics.blogspot.com/ We wanted to save energy, and create convenience, by adding motion sensors to our lighting circuits. Maybe you want some notification of an intruder. Both can be done with a PIR Motion sensor.  When I walk into a room, the lights come on automatically, and when I leave, shut off after a short period of time. You can choose how long that time delay is in the code. No more fumbling for a light switch in the dark with ...

LDR Engineering LDR (Light dependent resistor) Engineering is a technique of making several electronics circuits following the logic of a simple light and dark sensor using transistors, 555 IC and 741 IC. Out of several optical sensors, light dependent resistor can be used for making light/dark sensors. A dark sensor switches on transistor or LED whenever the incident light intensity is decreased, whereas a light sensor works in opposite way. In LDR Engineering, we first understand the ...

This sunlight-controlled lamp uses a light-dependent resistor (LDR) as the sunlight sensor and a total of 25 high-brightness white LEDs. Separate resistors are connected in series with each row of the LEDs. The working of the circuit is very simple. During daytime, light falls on the LDR1 and it offers a low resistance. As a …

Gerard's project! The Arduswitch reinvents the common light switch. With home automation being the next big thing, the open source community now has an Arduino-based smart switch. Using WiFi, you can network all the switches in your home from the comfort of your computer. Using the exit detection sensor, you can also see if anyone is in a room. The Arduswitch has an arduino, screen, WiFi, and relay on one circuit-board that fits nicely in a light switch box. Watch for the Kickstarter!
