The next phase in the development of our first alarm system was to move the components from the breadboard we had been using for prototyping to a perforated board on which we could solder the components and install it in my son’s room. To do this, you will first need to learn how to solder and there are some great online soldering tutorials such as the one below.
I personally chose a 15 watt soldering iron as I will only be using it to solder electronic components and the lower power should help protect the components from being damaged through exposure to too much heat. I recommend that you also purchase a vacuum de-soldering tool and a decent stand. What I have also found important is a third hand such as the one pictured below. This is a great tool for holding your board while soldering components onto it.
After a few minutes of practice, we were able to construct the simple alarm circuit described in a previous post onto a perforated board with little difficulty. The final result can be seen below.
