// The target MCU is an Microchip/Atmel ATmega328P, configured to behave like an Arduino Uno // The Arduometer PCB is designed to accept a Sparkfun FTDI Basic USB-UART bridge and to be programmed ...

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 ...

Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...

Arduinoを使ってシンセサイザーを作っているのですが、いわゆるツマミを使ったアナログ入力によってパラメーターをコントロールするには入力PINが足りません。そこでアナログマルチプレクサ（MUX）を導入する事になりました。 MUXの情報は、ネット上を ...

Little Bird Electronics posted an article about using an analog voltage reference with Arduino. This is a tool available when using an analog-to-digital converter. By setting up either an internal or ...

An analogue meter on a 1.8" ST7735 TFT 128 x 160 color screen The meter graphic function works best with slowly changing values without large rapid changes. This ...

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 ...
