In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

Environmental sensing technology has become increasingly vital in today’s world, where understanding and monitoring air quality and environmental conditions are crucial for sustainability and safety.

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. [Udo] hit upon the idea of pulsing a laser pointer and measuring the time of the ...

Arduino 101 is getting an LED to flash. From there you have a world of options for control, from MOSFETs to relays, solenoids and motors, all kinds of outputs. Here, we’re going to take a quick look ...
