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 ...

I settled on looking at some alternatives for doing an analog to digital conversion using successive approximation. A virtual potentiometer provides an input voltage.

Becky Stern shows you how to use digital and analog inputs when building Arduino circuits, including controlling LEDs using pushbuttons and potentiometers.

Electronic engineers, developers and hobbyists looking for a fully featured Arduino Mega compatible PLC may be interested in a new Indiegogo campaign ...

Consequently, both high-side and low-side switches can be read as digital inputs using the chip’s output pins. Also, the inherent transient protection provided in the chip’s output circuit ...
