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 ...
