Hey guys!
Im trying to do a mockup of the Stranger Things lights-on-the-wall for communicating with ghosts, its for a party. Im using a Ouija board. It will have a push button, which any guest can press and a random message will be displayed via the lights turning on and off. I have an Arduino One, which has 13 Digital I/O and 6 Analog which I can also use as Output. So I can use 17 Digital Outputs for controlling 17 Letters (which Im sure will be enough) and 1 for the Push Button.
I already did tests with LEDS and everything seems ok.
BUT
I bought a 100 Minilight series, and im trying to connect one of those minilights to Arduino, the only problem is that I am not being able to turn them on. Firs I tried to use resistors, since I read that this should use only 2.5v, and nothing. Then I took off the resistors, and the light turned on but VERY dim. Just as an experiment, I conected it to the 5v pin and it turned on ok! This surprised me a lot, since I understand that the Digital I/O output also 5v....
What am I missing??
I DID turn them into OUTPUT by pinMode(pinX, OUTPUT)
Any Help???
Thanks!!
