The inbuilt LED is also used which is directly connected in the board to pin 13. The relay is connected to pin A4. /* * Pin Description */ int Touch_Sensor = A5; int LED = 13; int Relay = A4; Define ...

This digital output can be input to a microprocessor where illuminance (ambient light level) in lux is derived using an empirical formula to approximate the human eye response. Commonly available ...

This circuit shows how to use an ordinary LED as a light sensor. It makes use of the photovoltaic voltage developed across the LED when it is exposed to. Aspencore ... Arduino Uno is a robust choice ...

While Arduino can provide power to LED light strips, you’ll want to use an external power supply to avoid overloading the Arduino board. Most LED light strips require a voltage between 12V and 24V, ...

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… ...
