Hello, I'm fairly new to the electronics hobby but I am having allot of fun learning .
I need some help designing what I think is probably a very simple circut for someone more experienced than my self.
What I need to build is a circuit that will flash a 12 volt lamp and at the same time buzz a small piezo buzzer.. And I need that to happen every 20 to 45 seconds or so continuously while the circut is turned on ..The duration of the flash and buzz can be any where from 2 to 5 seconds give or take.
I will be using 12vdc from a car battery for power.
If someone could point me in the right direction on how to do this I would greatly appreciate your help.
I guess I would need to build some type of timer circut that basically would allow 12volts to pass to the buzzer and lamp for 2 to 5 seconds or so every 20 to 45 seconds.
Can someone give me some advise on how I would build such a circut or maybe someone knows where there may be schematics that could help me.
Thanks.............Dave
