If you rotate the knob, numbers will count up and down on the display.

With this Mini Kit you will learn, how to connect a seven segment led display and a rotary encoder.

You will need a micro controller like the Arduino (not included) to run it.


1x   mini breadboard
1x   7 segment display (common anode)
1x   knob
1x   wire set
