You can make usual keypads for enter numbers, symbols, or navigate and selections in the program. There are pull-up resistors of different values for each button. This makes it possible to connect all the 16 keys to taking only one analog port of the microcontroller. The button consists of two parts: a cap, which can be applied to any character, and a transparent cover which can prevent blurring of the text and add light.\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e \u003c\/div\u003e\u003cdiv\u003e\u003cstrong\u003e\u003cspan style=\"font-size:14px;\"\u003eConnection:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/div\u003e\u003cdiv\u003e \u003c\/div\u003e\u003cdiv\u003e\n\u003cspan style=\"font-size:14px;\"\u003eAfter connecting power to the module and pressing at least one key contact at \"OUT\" will stress the appropriate level.
