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.
