    Hello!

    I am new to the forum and I have been trying to put together a circuit for the past couple days with no luck and have just about gone crazy...

    I need to be able to control 3 individual LEDs with one push button.

    For example, I push the button once, LED 1 comes on. I push the button again LED 1 goes off and LED 2 goes on. I push the button again, LED 2 goes off and LED 3 goes on. I push the button again, LED 3 goes off. I push the button again and the cycle starts back at LED 1...

    I am not 100% electronic literate, although I have taken basic electronic courses, so for the most part I can understand and intemperate circuit diagrams.

    I wish to keep the circuit as basic as possible, with most of the components being available at radio shack, or online.

    PLEASE, ANY help would be appreciated! Even if someone knows of a similar circuit that I could start off with looking at would be great.

    Thanks!

    No, only the counter. However, it doesn't have much output current, if you want brighter LEDs you need to add a driver for each LED.

    I will use a 8 pin microcontroller with build-in oscillator. ATtiny, PIC, or STC15F02. the circuit is simpler than a cd 4017, but needs simple program

    What exactly is required to program a microcontroller?

    I'd forget the microcontroller and go with that 4017 circuit, less stuff required in the long run.

    Additionally, using a button as the clock via a transistor is a fantastic idea, inspirational, my mind is alive with new ideas for circuits now!

    Agreed!

    Ordered components online today, so hopefully by Friday I will have a working functional circuit.
