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 ...

Usuallyyour meter will be bought or adapted for a specific measurement and youwill not have to make special efforts to get it to read what you want.Or your schematic will specify the sensitivity of ...

Electric utilities across the world have been transitioning their meters from the induction analog style with a distinctive spinning disc to digital “smart” meters which aren’t as aesthetically ...

This article describes the simple setup and explains the code to drive analog meters using PWM outputs from an Arduino and the LCD Smartie program. They also replace the meter face to show the proper ...

Our community never seems to tire of clock builds. There are seemingly infinite ways to mark the passage of time, and finding unique ways to display it is endlessly fascinating. There’s something ...

The digital prototype breadboard was an Arduino Uno R3 running an example program called “tonePitchFollower,” which is equivalent to a VFC. The circuit still needs op amps to buffer and amplify the ...
