Keypads are one of the most fundamental devices when making a micro-controller based system. Simple 4×4 keypads are easy to use and allow students to apply fundamental concepts of data acquisition, hence they are very popular in the electronic engineering community. With so many available in the market today, we decided to make a list of the ten best keypads for Arduino available in the market today.
10. SunFounder 4×4 16 Keys Matrix Keypad(5.99$)
