4 x 5 matrix keypad With LEDs


This matrix keypad is great for when you need quite a bit of buttons on your Arduino project. What makes this great is the fact that the top 16 buttons are all read from only 8 digital pins. While the four red buttons are read individually making them useful for a menu selection because they require less code to read them. Making them a little faster to read. As an added bonus there are 8 LEDs for a status indication for instance.
