Some Arduino (hardware) Tips

To help avoid losing hair I recommend wearing a helmet (joking!!)

I thought I share some Hardware issues I came across while bashing my head on the wall a few times.

1) If you are going to power your Arduino via USB power watch out how much
current you are going to consume especially when using a Shield(s).

Use a good quality USB cable (not those thin cables) but if in doubt if you are not sure
about exceeding the current don't waste your time, use a descent clean Power supply which
will save you many hours of fustration !.

2) Be warned, at times Headers can cause some problems, some are Brass, some gold plated
and some are rubbish. Occasionally use some good electronics cleaner (spray) and give the Pins/Sockets a
clean.

3)Make sure if you use a Breadboard its fairly new and has good contacts.

4) If using cable male/female jumpers use a descent gauge wire (but not too stiff).

BTW Excellent new Forum Section added !
