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.

Use Rotary Potentiometer To Drive Solid-State Volume Control Jan. 20, 2003 This design idea details how a standard volume control can be replaced by its solid-state equivalent.

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 ...

The FPGA communicates via SPI with an Arduino master controller which communicates to a PC using a serial interface. This is [s-ol]’s first time diving into an FPGA project and it looks like he ...
