46  Using Arduino / Programming Questions / Re: ah man Noob asking a question again... on: July 09, 2014, 05:31:17 pm
And your question is?
if (buttonPushCounter == 0);  <------- no ;
This isn't very functional.

Have you learned about "switch case"

what orientation
Yes, majenko, OP shows it backwards.

Use a 7805!

I always use the MAX7219 (can drive 8 digits however these are common cathode displays).
Very easy to use with https://www.sparkfun.com/products/12710

Will you be using the toner transfer or the photographic method?

So you want: the Battery, Arduino, SD card and camera to fit into a altoids tin?
51  Using Arduino / Project Guidance / Re: Camera and storage system for arduino on: July 09, 2014, 02:40:26 pm
What have you found that fits the size you need?
What is your maximum size?

Maybe the board circuit touched something metal.
53  Using Arduino / LEDs and Multiplexing / Re: Problem with CD74HC* Multiplexer/Demultiplexer on: July 09, 2014, 12:36:42 am
Are you saying if you select an input (which is high) then select another input (which is low) the pin on the controller is always high?

You need a fly-back diode over an inductive load. Always.
When talking about DC of course.

It seems I did make the simple mistake originally of having the 441 in upside down. I designed the pcb and knew I needed to put it in facing opposite of the 328 and when I put it in the socket I did not.
Experience varies directly with equipment ruined.
And
Always blame yourself.

splices should be done in an enclosed junction or receptacle box.
Must be accessible!

Maybe change the title of the post, add "It was my setup".
