He’s converted a mouse into a tuning dial. The scroll wheel on a mouse is nothing more than a rotary encoder, and can easily be used as a sort of tuning knob. Replacing it with a better encoder ...

The Arduino Nano Connector Carrier is a compact add-on board designed for the Arduino Nano boards to allow easy connection to ...

It’s fair to say that there can’t be many developers who have found the need for a rotary telephone dial as a peripheral for their Linux computer, but in case you are among them you might find ...

For example the they should all share an IO device such as a 23017 or an 8574, or if on arduino pins, all the A pins must be interrupt driven. Secondly, there is a hard limit on the number defined by ...

Abstract: This paper presents a single-excitation absolute capacitive rotary encoder that is small in size, lightweight, robust, and highly precise. The encoder consists of two plates: a rotor and a ...

4 and 19 pins are used to adjust the display contrast through a resistor. I use a 1 Mega Ohm variable resistor. Acceptable contrast ~270kOm.

The Banana Pi BPI-Forge1, also known as the ArmSoM Forge1, is an industrial SBC (single board computer) powered by the Rockchip RK3506J triple-core Cortex-A7 processor designed for Smart Audio, HMI, ...
