Great switch matrix
These are a little small but work great for breadboarding a project. Fast delivery and the switch matrix seems to be of excellent quality.
The 4 X 4 Matrix Keypad (RM0947) is a very simple one from have 16 tactile keys connected to the male headers across the resisters on the same board. It is very small and easy to carry. Its simplicity is hexadecimal to give the power to the keypad and connect the headers to the microcontroller's input port with whenever pin female connecting wire. When one tactile key is pressed its corresponding pin with Rows and column intersection gets high logic.
The connection to the keypad is divided into rows and columns. There are four rows and 4 columns that provides HexaDecimal Output is generated whenever any switch is pressed. The hexadecimal generated can be sent directly to the control unit for logical operation.
This 4 X 4 matrix keypad is compatible with most of the controller boards available on Robocraze.com that ranges from 8051 to Arduino Boards. Since the Output and the input of the keypad is digital in nature so, it can also be interfaced to motor driver circuit available on Robocraze.com.
