Hi to all
Thanks for responding to my questions, I must
apologize for my explanations I'm in a learning process about
electronics. I'll be running a power adapter from 240 AC input
Converting into adjustable 3v -12v DC output ,current is 1amp but will
probably run the 555 timer cover the maximum voltage of one of the
toys(9v) the other three toys in the circuit will run at 1x 3v and 2x
6v with each toy been activated with a independent push button switch
..The circuit I would like to build is for a 3yr old girl with multiple
physical and intellectual disabilities , she is able to push buttons;
which stimulates her with color and sound. My aim is build a
electronical unit in which I'm able interchange various toys with
various voltages from 3-9V either home made by myself (DC transistor
radio, motorized bells) or bought, that will help stimulate her
development.
The 548 transistor I referred to is a NPN the full info. is BC 548
-506 .The trigger switch I refer to is what I understand is called a
toggle switch which sends a pulse through pin 2 of the 555 timer you
can find a example of this circuit at
http://www.kpsec.freeuk.com/breadb.htm this will give you some idea of
what I'm talking about. To this circuit I would to add 4 toggle type
switches to activate and interchange 4 different toys which use volts
between 3-9V.
I hope this makes it a little easier to understand what I'm trying to
achieve if you need more clarification /information please let me know
..If you have some schematics for this idea is possible to send in
format similar to the http:// example I have given you as I find it
difficult to understand schematics in the format that has been sent me.
Thank you
Regards
Mark
