Okay, I'm fairly new to arduino and I recently make a binary clock similar to the Evil Genius example (lilypad).
I moved the time adjustment button to pin 11 (as it was open), then added a Real Time Clock to A$ and A% so it appears at though all my pins are sued up.... Except 0/RX.
Is it possible to connect a CDS cell to either 0 or to a3 (move the LED + to 0) and then add in a CDS cell to dim the LEDS when it is dark? They are very bright. Can the (-) side the LEDs be turned on and off to produce a dimming effect on all of the LEDs?
I may have to create a bank of LEDs and start alternating power to free up some pins?
Does anyone out there have code or build instructions for a digital clock? I want to play with these as well.....!
I don't know why I am having so much fun with trying to "reinvent" the clock lately, but I think I'm going overboard.
I'm open to suggestions....
