So, I have an interesting project going on. I have a source that sends a 12 volt trigger signal. I need this trigger signal to 1. Turn on 2 strips of LEDs. 2. Trigger an electric motor that has to run for a specified amount of time. When the source sends this trigger signal again I need the electric motor to run for a specified time, but backwards. And the LED's need to turn off. I was looking at buying two of the following LED strips: http://shop.ebay.com/i.html?rt=nc&LH_BIN=1&_nkw=LED+Strip+5+m&_stpos=&_trksid=p3286.c0.m301&gbr=1 and then connecting them in parallel so they could be powered off the PSU in my computer. and then using this switch to control them http://cgi.ebay.com/NEW-12-VOLT-5-P...221?pt=LH_DefaultDomain_0&hash=item3f0160a3ad The electric motor would be a low-RPM high torque model. Can you guys help me? I can do basic soldering and have some basic knowledge of electronics.
are you planning on using any sort of microcontrollers? it would be way easier if you did. just curious about your source, i assume that you want the magical device doing stuff when a person is entering the room, and then stop doing the magical stuff when the person exits the room. does your source take direction under consideration? (imagine you enter the room, magic box says "yay", and then your friend enters the room, magic box says "buu" rather than just ignore your friend). if you're not using microcontrollers, you'll need some circuitry, and a few components extra.
It's actually a projector that is the trigger. When it's turned on it sends a 12v signal through a plug on the back. I want it to turn on LED's around a projector screen and lower my curtains. Then when I turn the projector off, it should turn off the LED's and raise the curtains. I know nothing about microcontrollers but I am eager to learn
well this certainly simplifies the "problem" alot there is no need for microcontrollers. i'll sketch something up, hold on. (man, i thought you'd need a bunch of gates, timers and whatnots)
sorry, had some work to do (oddly enough) there we go. this is basically what you want. trigger goes high, motor starts driving the curtain forward until it hits the switch where it breaks. trigger goes low, the inverter kicks in activating the relay, driving the motor backwards until it hits the switch where it breaks. the trigger signal could run the leds i believe.
