DigiPot – Rotary Encoder Digital Potentiometer

Description The “potentiometer” is actually a rotary encoder (TW-700198) connected to a microcontroller that reads the signal from it and convert it to a value that is displayed on 7-segment displays. The value also is sent via i2c/spi/serial/usb to the host. Also 3 LED and included for status indication. The board is planned to either be operated in an autonomous mode where the display is updated by the bo ...
