Rotary encoder vs potentiometer. A rotary encoder is a wonderful digital alternative to the old analog potentiometers. Rotary encoders are useful as rotation sensors (or selectors) and look similar to ...

Arduino Uno + potentiometer + OLED == virtual circular dial. Call it synchronicity, or manually setting a 16-bit number in an Arduino, or how to turn an OLED into a rotary dial... What am I talking ...

At the heart of the device is a AD9833 waveform generator; with the Arduino, rotary encoder, ... uses a X9C104P 100KOhm 8-bit digital potentiometer as a voltage divider on the chip’s output.

We set the potentiometer pin as 0 (A0 on the Arduino Uno board), the CONTROL variable is the voltage that is used to cotrol the led brightness of the speed of the fan. In the setup() function the ...

Potentiometers fall short in many different ways, ... One of the issues of hooking up rotary encoders directly to a Arduino is the overhead it requires.

Arduino Uno + potentiometer + OLED == virtual circular dial. Call it synchronicity, or manually setting a 16-bit number in an Arduino, or how to turn an OLED into a rotary dial... What am I talking ...
