Want to prototype your own security system? You may have seen Magnetic contact switches being sold at stores, but you could build your own, too! Most of them are used as a way to detect if a door or window is open. Basically one side has a Reed Switch in it and other side has a magnet in it. When the two side get close to each other, the two wires become connected and this can be read just like a button press. How come? A reed switch is an electrical switch which is operated when a magnetic field is brought near to it! These low-cost Reed Switch Modules also come with a mounting hole for easy fixed installation.
