What I am trying to do is build a timer that will control two separate circuits, one light circuit and one motor circuit ( on/off... on/off ) for let's say a five minute cycle.
I am starting with a DC motor revolving tie rack, ( I have two... one uses 3 "C" cells batteries and one uses 4 ).....but I need the motor to come ON
for, let's say one second/ OFF
for ten.... ( these times may change slightly) repeat for five minutes or whatever completes one or more entire revolutions. Another option was to slow the speed way, way down by reducing the DC voltage but when I tried, there comes a point where the thing just doesn't revolve.
The second timer function is to activate a light source ON
for the same five minute cycle. I want to use an available cold cathode fluorescent light kit that would serve my purpose. The kit comes with an inverter that supplies a 12V DC starting voltage up to 900-950 vrms. Then the voltage will drop supplying the lamp a constant current of 4-9 mA at 40-50 KHz.
After the five minutes the systems shuts off until the button is pushed again.
The 556 timer doesn't seem to meet my needs..the motor on/off times will be the same and I can't make a timed cycle. Either once on or it keeps cycling until I turn it off.
I tried reading about programmable chips which opens a a big can of worms. So, before I invest too much more I thought it wiser to seek a little help. What started out as an interesting project has left me feeling pretty dumb.
Hope this made sense and thanks if anyone can point me in the right direction.
