Working on an Arduino project for a magazine article. Was just about working right, and I decided to make a small change in the program. Now it's completely doing nothing like it's supposed to. "What?" Unmade the change and it's completely naff. Fiddled around with it for quite a while before I noticed the outputs of two of my IR detectors were always low. "Hmm, there's no VCC to these two."

 

A stupid wire on my breadboard had gone bad!?!?! Replaced the wire and the changed program works as I expected it to work hours ago. Who'd have thought a program change would cause a wire to go bad

When wires get too old they lose their conductivity.

What do programmers lose when they get too old?

Realise it would not have helped here but you might want to explore the use of a revision control system (SVN, Git, etc.) which would allow you to quickly revert to a working version if you had made changes that broke the code. The important thing is to commit changes often as you reach each next "working step".

My "Working Steps" tend to be very small.

Might we even say "tip toe"?

You can put lipstick on a pig, but it is still a pig.

I've never met a pig I didn't like, as long as you have some salt and pepper.

every time I start working on code, or if I reach a point were things seem to work I make a zip file of the entire project. Then when I think things are really stable I make another zip file and put that apart. then zip the rest of the zip files and mark them as old.

If I have a couple of 'old' zip files and stables I just throw away the oldest versions.

 

I also develop code small steps at a time, just because it seems that every time I do a major change things stop working because I forgot a small thing and then look for the problem for hours.

The "wire" went bad!  or the contact in the BB got flaky and moving (replacing) the wire brightened the contact for a few more hours!  q:-(  I so dis-like BB's!)
