Simple RFID based Door Lock using Arduino

Its quiet fun to work with RFID based projects! In the previous article, we saw how to interface RFID with Arduino. Interfacing is the first step to create any useful project. So why don’t we create an RFID based Access Control System or an RFID based Door Lock using Arduino? The system I have designed here is a simple version of the project. This project can be enhanced with a lot of features (which I will ...

How to Text Yourself when your DSC PC1550 Home Security System Alarms

I have a home security system that was installed when my home was built in the early 1990’s. It is, or was until I modified it, a wired perimeter system with a single wired motion detector. The system is a DSC PC1550 and originally was monitored by a well known alarm system service, a three letter acronym beginning with the letter “A”. Anyway I stopped paying for the monitoring long ago. More recently I dec ...
