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 ...

Any high-performance engine needs to be cared for and properly monitored. Sometimes, factory gauges can be inaccurate or simply not specific enough for a modified car, so take a look at these ...

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 ...

As much as it might be easy to feel like the connection between car and driver is a spiritual one, some hard data needs to be communicated between the two. Gauges do that work by providing information ...

With so much data being thrown at our eyeballs these days, it’s worryingly easy for the actually important stuff to slip by occasionally. So when [Liam Jackson] wanted a way to visualize the number of ...

Powered by digital microprocessor-controlled rugged stepper motor drives • Seven LED illumination colors • Programmable warnings • Signal Playpack • Peaks • Built in data-logging on SD flash memory ...

You can get analog meters that are blank, in the sense that they need a series resistor to display voltage and amperage is usually done with a very low resistance resistor, typically half an ohm. You ...

Editor's note: If you're like us and can't bear to part with that crusty old (but magnificent) analog meter, David Ashton offers everything you want to know about these gems in this three-part series: ...

Like a rolling stone back in 1965, when Bob Dylan first sang about an uppity young lass that rode on a chrome horse with her diplomat, the instrument panel on the recently introduced 1965 Chevelle was ...

Stick-type pressure gauges resemble a ballpoint pen are simple and compact, and don't need batteries. Pressure is read off of a sliding scale proportional to the air pressure. Digital gauges have an ...
