In this article you will know: 1. How to make a keypad controlled by stm32. 2. How to make a Keypad without libraries on Arduino IDE. 3. How to make a midi controller using keypad and stm32. There are several midi software that can be controlled using a pc keyboard and you can use these keyboard modules for custom midi controllers. However the midi controller that uses the pc keyboard module will stop working when it is opening another window. For example, when you open notepad, the keyboard module will switch its function to a typing tool. Unlike the midi controller, it will still work as its function even though the controlled software is working in the background. In this article I will show you how to make your own midi controller at a very low cost but with luxurious quality. I provided a schematic of the keypad circuit to start this tutorial. Look at this picture, there are four pins on the column and four pins on the row, so we call this a 4x4 keypad. C1 is the first co...
