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 ...

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.

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 ...

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 ...

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 ...
