Learn step-by-step how to read the buttons pressed on a 4x4 matrix keypad. Course material: [ Ссылка ]
There are many kinds of matrix keypads. A flat one, the so-called membrane keypad, but there keypads with tactile switches available as well. Even the size can vary per model. Below, in the component section, there are all kinds of keypads listed with the sizes 4x3, 4x4, 4x1, 5x1, 6x1 and 3x4. They all work the same way: for each row and column there is a pin.
When you press a key, a row and column is connected. This makes two pins on the Arduino HIGH. In this way we can determine which button has been pressed. In this video I explain how you can use a keypad library to make your life easier.
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.
