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 , ...

Here, inspite of the I2C interface, just an analog input of the Arduino is used. Needless to say, a simple add-on hardware is necessary for this little experiment. The hardware is nothing but an ...

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. Last month we saw [Udo]’s blinkenlight shield that can be used as a lin… ...

As a biomedical equipment technician [Adam Outler] equipment needs to be in top working condition. The emergency room staff were complaining about erroneous noise on the electrocardiogram and it&#8… ...

The sensors trigger an Arduino to turn on LEDS on a nearby setup. In the video (which is after the break) you can see the entire thing in action -- which maker Joe says can eventually lead to a ...
