The Q5X sensor solves difficult distance-based applications, even at acute angles, at a range from 9.5 centimeters to 2 meters. The high-power laser sensor reliably detects difficult targets, ...

An Arduino can measure time, a coil and a resistor will create a delay proportional to the circuit values, and metal around the coil will change the coil’s inductance.

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...
