Now, there are several different types of programmable timers. Some are mechanical.
Some are digital. Some require only two wires, while some require more. Before you buy the timer, you will need to do a little investigation to determine which type of wiring you have, which will determine what type of timer you can use. Note, if you are not comfortable using a voltmeter to measure the voltage of household wiring, then you should probably leave this project to a professional electrician. The first thing to determine is whether the existing switch that you want to replace is a three-way switch or not.
A three-way switch is when two switches control the same light. This is often the case in a long hallway or staircase, where you can control the hallway light from either end. Three-way switch wiring is more complicated and will require a timer that is specifically for three-way switches. Luckily, most things that you would want to put a timer on, like a porch light, only have one switch controlling them.

Note that neutral is different than ground. The ground wire is often bare copper or sometimes green. When I opened my switch box, the wires looked like a plate of spaghetti. To make matters worse, many of the wires were covered in white paint so they all looked white. But, after some careful observation and some volt meter measurements, I was able to ascertain that I had all four wires.
That was good, because I had already purchased a timer that required four wires! The packaging or description should say what wires it requires. Also, if the timer is not battery-powered, it will need the neutral wire. Okay, now that that painful step is out of the way, I can start talking about the pros and cons of the different types of timers. Many two-wire timers require a battery, so watch out for that!!!
