Why can it not be controlled with PWM ?

Sorry, massive bugbear of mine is when people paste code into comments. Please use the correct formatting or use Pastebin for code.

You have a loop that repeats 3 times inside a loop that repeats 3 times so the whole thing will run 9 times.Apart from that I see nothing wrong with the code. it shoudl stop after 3 cycles.

The easiest way is to sacrifice an LED or two and connect them up to a variable power supply and increase the voltage till it pops. At the same time, measure the current draw across the LED.

Nice project but I have no idea why you have put it into such a massive box. Look at it, 90% of the box is empty space. Use an Arduino Nano and put the whole thing into a tiny box not much larger than the LCD display.

WHOLE battery, not HOLE battery.

I'm pretty sure we were all expcting one at the end of your instructable anyway.

"The version of Arduino we will create is "ATMEGA328 on a breadboard (8MHz internal clock)", or at least that's the menu entry for it in the Arduino Tools -> Board menu."This entry does not exist.

Great tutorial but I see no reason why 2 Arduino's have been used instead of just 1.
