Hi all,
Once again I'm back with an LED and a clock project.
This time a binary one, controlled with Arduino.
It's already built into a nice small mint-tin, powered by a 9V battery.
Items
I've included the circuit, don't have a picture of it yet. (I'm at work currently)
I'm still fine-tuning the program, I currently have a minute off every hour
It's counting to slow, but I think I know where the problem is.
Once I got it out, I'm planning to post it in the finished projects section.
Is there any way to calculate how long it can run on a battery?
Besides just plain trying it
Let me know what you peeps think of it, and if I can improve something for the next time =]
Greetz,
