Chronos controlled door lock

Addidis posted the above short video of his project controlling a door lock using the ez430-Chronos watch. He describes the hardware:

Chipkit MAX32 , 2 Xbees, Chronos Control center, and a Chronos watch controlling a servo. (I’m gonna hot glue it to my door knob lock switch and not have to use my key any more!)

The Chronos firmware is untouched, This uses the Chronos control center and some simple code for Arduino / Chipkit. I used Hyperterminal to connect to the Xbees, and then highlighted the terminal and the Chronos control center key presses are passed to the Xbee.

It is a combination of the serial switch case example and the servo example.

Addidis has shared the following Arduino sketch:

// Sweep
// by BARRAGAN
// This example code is in the public domain.

// NOTE: UART will be disabled when servo is attached to pin 0 or 1.

// Set the chronos to put out ‘u’ and ‘l’ for the keys you wish to use.

#include <Servo.h>

Servo myservo; // create servo object to control a servo
// a maximum of eight servo objects can be created
int inByte = 0;
int pos = 0; // variable to store the servo position

void setup()
{
Serial.begin(9600);
myservo.attach(9); // attaches the servo on pin 9 to the servo object
}

void loop()
{

if (Serial.available() > 0) {
// get incoming byte:
inByte = Serial.read();

switch (inByte){
case ‘u’:
myservo.write(0); // tell servo to go to position in variable ‘pos’
delay(15);
break;
case ‘l’:
myservo.write(180); // tell servo to go to position in variable ‘pos’
delay(15);
break;
delay(35);
}
inByte =0;
}
}
