Code in the Arduino sketch is then used to compute the actual voltage being measured. The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.

From the same source, I got this graph with an equation that relates the voltage from the sensor to turbidity! I made a few initial tests the other day, trying to have the DFR sensor module ...

“Arduino does not manage the buck converter module but only measures output voltage and current through a current sensor and then shows those values on a display. Power value is showed to ...

The Raspberry Pi is a credit card-sized computer capable of running full-fledged Linux distributions such as Raspberry Pi OS, ...

If you are interested in building your very own mini DIY LiDAR sensor for less than $40, capable of detecting objects in a 360° area, you may be interested in a new Arduino Instructables project ...
