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 ...

Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...

Engineers always want to get all they can from their circuits; this holds for analog-to-digital converters (ADCs). To maximize performance from an ADC, resolution is perhaps the primary spec to focus ...
