This project uses an Arduino board with a photoresistor sensor and a GSM shield to send an SMS message when the light level detected by the sensor falls below a certain threshold. Connect the GSM ...

Here is a traffic light system based on Arduino that can be used in a 3-way ond 4-way intersections. It has an additional blinking orange led that is used to signal when the pedestrians can cross the ...

Here is a simple Arduino Camping Light project. In this design, only one push button switch is used to control the light output (from a bunch of white LEDs) between off, dim, medium, and full ...

If you're into robotics or electronics, you've likely come across Arduino—a small microcontroller that can control sensors and motors for nifty DIY projects. Like the Raspberry Pi, the Arduino is ...
