Hello to all. I am a complete newbie here and am new to electronics in general. Trying to learn bits as I go along on an as need basis.
Attached is my first attempt at producing a PCB but I have zero confidence to get it actually made. (not sure if this is how I am supposed to link to my project????)

Things of concern;
1. When this is manufactured, will the holes be made for each component based on what I have or do I need to use the 'hole' function on every component hole?
2. For some reasons teh voltage regulator outline has been automatically created in yellow (I have assumed that teh yellow is what gets printed onto the final board). I only want to put a square around the 3 VR holes and label them something like 'In Gnd Out' and delete the pretty VR shape. I cannot work out how! Heeelp :)
3. Are there any glaring issues?
I originally developed the circuit using another program that allowed me to do a simulation. I then progressed to using a breadboard and doing real tests that seemed to work fine and now I am moving onto PCB production. I am therefore reasonably happy that the underlying circuit is OK but am hesitating pressing teh go button an manufacture.
As some background for anybody interested, my major project is developing a data-logging system for my race car. A sub-project of that is developing some Arduino magic to calculate engine RPM. I already have an induction sensor mounted that I need to use (yes Hall Effect would be much easier). I decided it would be easier to use a digital signal rather than an analogue one. The sine wave from the sensor can read up to +/-50v at redline which the Arduino definitely wouldn't like anyway. I am learning a heap but my head is spinning!!!!!!
