Thread: Multicolor crystal LED help.

    Default Multicolor crystal LED help.

    Hi,

    I tried to find a topic to help me but could not find one.

    I bought a multicolor LED (with only 2 pins) from the electronics store and I want it to change colours. I was told that it shows different colours depending on the voltage that I send to it. How would I go about having it circle through all the colors?

    I don't know what kind of board or accessory I need to control this.

    Thanks.

    Interesting. You might try putting a potentiometer on one of the leads to see if that will work. A benchtop PSU would certainly do the job, but they're not terribly portable.

    I would pull up the manufacturer's spec sheet for more detailed information.
    We all have to start somewhere. The journey is all the more impressive by our humble beginnings.
