## MotherShip Connection
This came from the Arduino Uno kit, one of the first actual projects where you program anything. Since I use JavaScript quite often, I decided to try and re-factor this code using the Johnny-Five IOT Node lib. Here is the original code
### original Arduino code
```java
/** THE MOTHERSHIP CONNECTION
* by Ben Redden
*/
int switchState = 0;
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(2, INPUT);
}
// the loop function runs over and over again forever
void loop() {
switchState = digitalRead(2);
if (switchState == LOW) {
// button isnt pressed
digitalWrite(3, HIGH); // green LED
digitalWrite(4, LOW); // red LED
digitalWrite(5, LOW); // red LED
}
else {
digitalWrite(3, LOW);
digitalWrite(4, LOW);
digitalWrite(5, HIGH);
delay(500);
digitalWrite(4, HIGH);
digitalWrite(5, LOW);
delay(500);
}
}
```
### Johnny-Five code (probably couldve been written more elegantly)
```javascript
'use strict'
/** THE MOTHERSHIP CONNECTION
* by Ben Redden
*/
const five = require("johnny-five"),
board = new five.Board();
board.on("ready", function(){
// create an Led on pins 3, 4 and 5
let red_led_one = new five.Led(4),
red_led_two = new five.Led(5),
green_led = new five.Led(3),
ignition_switch = new five.Switch(2);
// the green light is on (HIGH)
green_led.on();
// red led is off (LOW)
red_led_one.off();
red_led_two.off();
// do cool stuff when the switch is closed
ignition_switch.on("close", function() {
// turn the green off
green_led.off();
// make the red led blink fater
red_led_one.blink(325);
red_led_two.blink(325);
});
// do the opposite when you release the switch
ignition_switch.on("open", function() {
// turn em all off, except the green.. turn that back on
green_led.on();
red_led_one.stop().off();
red_led_two.stop().off();
});
});
```
