The project illustrates the driving of analog meters using PWM outputs from Arduino as well as the LCD Smartie program. A small current is typically required by meters to operate wherein a typical ...

We think it’s a great learning experience to tear back the veil of abstraction and learn a bit more about the hardware found on an Arduino board. This project is a great example. [Scott Daniels] takes ...

microcontroller into a (more or less) smooth DC voltage. In principle, a typical microcontroller can supply an average voltage range of 0 to 5 V via its PWM pins. But we need to convert the ...

Digital displays are useful for quick and accurate readout, but lots of people prefer the physical motion of a needle moving along a dial. For instance, many smartwatch users choose an analog face to ...

This file type includes high-resolution graphics and schematics when applicable. A common project requirement is to have an adjustable voltage regulator programmed to deliver a specific dc output.
