# Keyboard

![Keboard](https://dl.dropboxusercontent.com/s/8nrk4vs5pqrakeu/arduinolt2.jpg)

This is a library to use a toy / education laptop keyboard with Arduino.

The keyboard is 6 rows by 8 columns.

The 6 rows goes to 6 of the Arduinos io pins (with pull down resistors).

The 8 columns goes to a 4017 decade counter / johnson counter pins Q0 to Q7.

The Reset and Clock pins on the 4017 goes to Arduino io pins.

# install

Create a directory under your Arduino/libraries called "Keyboard"

Copy the Keyboard.cpp and Keyboard.h files to the directory.

Restart the Arduino IDE. 

#usage 

````Aeduino

#include 

//Decade Counter reset pin = Arduino pin 8

//Decade Counter clock pin = Arduino pin 9

//Keyboard row 1 = pin 2

//Keyboard row2 = pin 3

//Keyboard row3 = pin 4

//Keyboard row4 = pin 5

//Keyboard row5 = pin 6

//Keyboard row6 = pin 7

Keyboard kb(8,9,2,3,4,5,6,7);

void setup() {

  Serial.begin(9600);

}

void loop(){

  int c = kb.getChar();

  Serial.write(c);

}
