This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this Arduino ...

With such devices lower-value measurement becomes difficult, especially for DIY projects. Here is a circuit that can measure low voltages, starting one millivolt onwards, with better resolution.
