The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format that can be processed by the microcontroller. Here, we are feeding the input voltage ...

The Arduino slowly scans the sensor in a grid, taking readings along the way. A Processing application then takes each reading and compiles the final image.

Summing Up BMP280 from Bosch is a compact digital sensor that very accurately measures air pressure and simultaneously determines air temperature with reasonable accuracy. One advantage of this sensor ...

Using a small sensor, an Arduino Pro Mini, a relay, transformer, and an outlet box, he created a system that can detect the amount of water in the tree's tray and blink a morse code message when ...

[Artlav] wanted to build a digital camera, but CCDs are expensive and don’t respond well to all wavelengths of light. No problem, then, because with a photodiode, a few stepper motors, the ob… ...
