Hacking an alarm system keypad for other uses

One of the great things about the Arduino system is the ease in which it can interface with other devices. One example of this is ‘Caitsith2′ who has determined how a DSC PC1500RK alarm system control panel works and communicates. Originally it would have been connected to the alarm master control box, however using his examples it can communicate via the serial monitor and therefore can be controlled with an Arduino. For example:


Although this is a specific example, it shows what can be done with random devices found around the home or elsewhere with an Arduino. Or in this case – the Arduino could become the controller of the alarm system if still in place, opening up more advanced control and interface methods. For the example Arduino code, visithere. And we’re on twitter and Google+, so follow us for news and product updates as well. 


When experimenting with your Arduino board by interfacing with the “outside world”, it can be difficult and time consuming to mess about connecting wires of various sizes to the board. However with the Freetronics Terminal Shield for Arduino – the problem is solved:

Apart from having a larger than normal prototyping area, there are terminal blocks for every Arduino pin, three LEDs for general use and a reset button on the shield. Great for experimenting and fast I/O connections – so order yours today
