What are the transistors?
There are no resistors on the outputs of the Arduino.

Would you go over the lines with a darker pencil/pen and rotate the image 90' ccw?
48  Using Arduino / Installation & Troubleshooting / Re: Uno external power supply problem on: April 01, 2014, 11:23:26 am
When you attach external power to the power connector and not plugged into USB, measure the voltage on the 5 volt header pin.
What do you get?

I cannot see it on my iPad.
Attach a jpg or png image to your next post.

It has extra A7 and A8 (see your photo).
That is A6, not A8, a bit blurry though.

You'll have to use a relay.

@Crossroads, what page is that on?
53  Using Arduino / Microcontrollers / Re: what if I remove ATmega328 from Arduino UNO R3? on: April 01, 2014, 12:17:05 am
Yes.
Buy some extra controllers for projects like this.

What version of IDE are you using?
56  Using Arduino / Sensors / Re: Arduino Micro as "piggyback" fuel controller on: March 31, 2014, 11:15:07 pm
If you want a voltage out you need a DAC.
57  Using Arduino / Programming Questions / Re: Serial Transmition Stopping? on: March 31, 2014, 11:10:24 pm
Try:
unsigned long lastSample = 0;
58  Using Arduino / Project Guidance / Re: Arduino Pro Mini Connectivity and Power Questions on: March 31, 2014, 10:56:37 pm
The pro will take the current it needs.
Make sure the voltage is 5 volts, and observe the polarity.
Note, always follow the maximum pin current of 20ma or a total for the chip of I believe 150ma.
59  Using Arduino / General Electronics / Re: General Resistor Question on: March 31, 2014, 10:51:15 pm
As long as the current going though the LED also goes trough the series resistor.


60  Using Arduino / Programming Questions / Re: please help trying to use the "if" Statement on: March 31, 2014, 10:38:59 pm
Try:

if (delayPeriod == 100 )
{
delayPeriod = 10;
}
