Electronic Siren 555 timers are generally used to generate timing pulse. It can be either monostable or bistable. Here the 555 timers are used somewhat differently. Its output is fed to its input, hence it works just like an oscillator. Two timers are combined to generate the desired sound.
The "HEE HAW" Electronic Siren values of resistors and capacitors can be changed to get some different frequencies of output. These Electronic Siren timers are like having your friend on-call 24/7, ready to rock at a moment's notice! They make the most out of every last minute of your fireworks display; they save you time and money by fully automating old-school alarm clocks. It is also perfect for porch lights, holiday displays, or anything else that needs some custom timing down pat.
