And you have also marked "To white LED", "To red LED" and "To blue LED". In the three alternating flasher circuits, you have referenced the square, diamond and star, but also shown single or double LEDs next to them. Then you have three alternating flasher circuits and a one-of-three circuit these four circuits are enabled by four DIP switches. You seem to have five groups of LEDs at the bottom right, identified with three symbols - square, diamond and star. Unfortunately that schematic is still not clear. Thanks for making an effort to clarify things. Circuit "D" runs all of the LEDs when activated. Circuit "C" is connected only to White LEDs.Įxcept for circuit "D", the individual circuits all run 13 LEDs each. Circuit "B" is connected to only Red LEDs. Circuit "A" is only connected to Blue LEDs. Circuit "D" is connected to all the LEDs.

Now, "A", "B", "C" and "D" are the LED driver circuits. I modified a CD Drive to house the built. The circuit runs on 12VDC from a Molex plug inside the PC. I have attached a very, very, very, very, very, very simple diagram of the circuit I built.
I just wanted to "improve" on my own build. So, he wanted something that mimicks the police lights inside his PC. My one friend asked me to build a circuit for him that he can use inside his PC. Ok, I'll try to explain what the build should do. I do have a CD4017 decade counter, but not sure about the 4024. But, everything else is basically what I want. I just want to take away the clutter at the dip switch. Well, I guess I should have been a bit more specific. This gives the following output sequence: Your description of what you want is not clear, but if you want an eight-step sequence giving all possible combinations of three control signals, you can use a binary counter such as a CD4024 instead of the CD4017. If you want two or more circuits to be activated on certain steps, you can use diode (or resistor) gating to combine outputs. This can be used to turn on a transistor to supply power to your other circuitry. On each step, the relevant output goes high (positive voltage). This IC needs a power source in the range 3~15V DC and can be configured to cycle through any number of steps from 2 to 10. But it can be done fairly easily using a CD4017 decade counter. If you want to keep the existing LED "chaser" circuits but add a control circuit, you are increasing clutter, not reducing it. A 40-pin device might be able to drive all your LEDs directly, or you might need expansion and/or driver circuitry, depending on how many LEDs you have and how much current you're running through them. The best option to minimise clutter and maximise the ease of making future changes would be to use a microcontroller such as a PIC.
If you want to de-clutter your build, you should take a step back and define exactly what you want to do. My question is this, How can I accomplish this without a complete redesign of my build? Is there a way? You can see the pattern? Button press number 7 will be power off. If the button is pressed the fourth time, "circuit 1" and "circuit 2" both de-activate and "circuit 3" activates. When the button is pressed a third time, "circuit 1" activates while "circuit 2" remains active. When the button is pressed again, "circuit 1" de-activates and "circuit 2" activates. I would also like the following to happen, when the button is pressed, "circuit 1" activates. I want to take the dip switch selector away, and replace it with a pushbutton switch that is normally open. Three smaller builds controlling just two LEDs, and 1 main build controlling all LEDs.Īll of these smaller builds are isolated from each other via a dip switch selector being used as power switches. But, I wanna take some clutter away from my build. So here's the circuit that I borrowed and adapted to my needs. So, for circuits, I borrow from the 'net.
