Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...

This project is a simple modification of the LightGauge project. Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino.

The first in a family of CMOS voltage comparators, the ALD2321 claims a 50,000:1 improvement in small signal threshold detection when compared to current 200- to 1,000-pW technologies. The device ...
