Smart Security System

Do you ever feel unsafe in your own home, or do you need to protect your company? Maybe you could make a security system so all of these problems gets solved. In this instructable i tell you how. I mounted all the parts on a wooden plank for demonstration purposes, you should mount it where you need it (the arduino part at the wall where you can reach it, the main board somewhere out of direct range, the siren and the strobe where you want it and the sensors in the rooms you want to protect.”
