USE ONLY 1 PIN TO READ 4 BUTTONS (KC11B04 4X1 AD KEYPAD) - Arduino tutorial #29
A KC11B04 analog AD 4x1 keypad only needs a single analog pin to readout 4 different buttons. The big advantage is that you save 3 pins, which you can now use for other components. In this video I describe how to read the analog AD KC11B04 4x1 keypad and how this keypad uses resistors to split the different buttons. The keypad is called an AD-keypad since it has a single AD-pin (Analog Data).
The Arduino for beginners tutorials series guides you through the world of Arduino. A video is around 10 minutes and shows you step-by-step how to build the circuit and write the code. The website contains the course material, circuit diagram, Arduino code and shopping list of all the components used in the tutorial.
