The Yocto-Knob-C device provides easy reading of 5 input buttons, contacts, switches, or potentiometers (knobs) from USB. It is a kind of USB analog-to-digital converter (adc). You can also use it to read any analog resistive sensor, such as photodiodes.
On the device, 5 tiny LEDs constantly show the value of the 5 inputs, and 5 micro-switches connected in parallel to the inputs simplify the testing of your project.
If you need more than 5 channels, you might be interested in the Yocto-MaxiKnob.
USB cables and enclosures to be ordered separately.
