I'm a very new beginner in Arduino. a friend told me it might be the right solution for a clock I want to design, and I thought of asking your advice here:
I want to build a clock, which must run on batteries rather than an electricity cord.
- The Clock has 27 LED lights, of 3 different colors.
- Every four seconds, the clock updates its display, causing some of the LEDs to turn on or off.
- In average, at any given moment, only half of the LEDs are turned on.
- The device doesn't have to do anything else beside running this clock program.
Can you guide me about the right Arduino components I should buy for running such a clock?
How long do you think such a clock can run on batteries?
Thank you very much in advanced,
