Laptop Battery Analyzer /Recycler

Step 4:

4) After getting the parts together First thing to do is prep and connect the LCD dispaly , I used the basic setup of an LCD display as seen  on the Ardunio tutorial page ( http://arduino.cc/en/Tutorial/LiquidCrystal ) I however do not use a Potentiometer for brightness control, I just connect Pin 3 to Ground . I also Do not use the same Pins. I don't use the High end Pins, because i had ideas of putting an Ethernet/SD card Shield on and recording the data from each Battery as it was being tested , that however has not come to fruition .

back to the matter at hand the LCD display .
Pin   Destination
1   - GND
2    + 5
3       GND
4   -  Digital Pin 2
5 -     Digital Pin 3
6,7,8,9,10  No connection
11   - Digital Pin 5
12  -  Digital Pin 6
13 - Digital Pin 7
14    Digital Pin  8
15     + 5  
16 -- GND 
that will take care of wiring the LCD
