Wasting energy by keeping the street lights on all night, we can build an affordable, high-performance smart street light system with the Arduino, LDR sensors. In this article, we'll discover how to ...

As photons (light) land on the detector, the resistance will decrease. The more light is we will have a lower resistance. By reading different values from the sensor, we can detect if is it light , ...

The massive quantity of electricity gets used in lights through roadways in India. Still, roadways remain empty for nearly all of the day after at night, with a handful of cars passing during the ...

The low-powered device consists of a PIC micro-controller, an LDR (light dependent resistor) for light sensing and a low current relay which switches between the two modes.

TK has combined a PIR with an Arduino to create a smart safety light for the house or workshop. Follow along as this gets built out into a more extensive project.
