Description

The Yocto-Knob 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). It can also be used 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.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub-GSM.

USB cables and enclosure to be ordered separately.
