audioguru Posted October 16, 2009 Report Share Posted October 16, 2009 The same as I told you on another website and somebody else told you on yet another website: Use the relay that is on the original Ultrasonic Radar project. The relay is driven by TR2.One set of relay contacts can turn on the siren and another set of relay contacts can apply power to the stobe light circuit and to this fluorescent light.Please do not make so many threads on so many websites about this project.

Hero999 Posted October 16, 2009 Report Share Posted October 16, 2009 I don't know where you get the patience from.I thought about responding, then I decided against it as the original poster doesn't seem to be making any effort to try to figure it out for himself.Of course you could add an additional transistor to control the siren, rather than having two relay contacts.
