The other circuit on the right is a sound modulation with 2 555- timers to get a loud and high pitched alarm sound as an alarm system for the back door of my house. | The other circuit on the right is a sound modulation with 2 555- timers to get a loud and high pitched alarm sound as an alarm system for the back door of my house. | ||
