Does anybody know how the neat breadboard schematics used by jeremy blum or in some of the examples on here are developed??

Thank you so much for the help! Got it to work perfectly

Hi Lefty Thanks for the quick reply,

Im using the arduino for just a small aspect of my project so I would only be a novice when it comes to programming so please bear with me.
Ive used the following code but seem to be getting very fluctuating readings:

int analogPin = 2;     //  connected to analog pin 2
                       // outside leads to ground and +5V

int samples[8];
int i;
int pressure=analogRead(analogPin);

void setup()
  Serial.begin(9600);          //  setup serial

void loop()
  for (i=0;i<=7;i++){ // gets 8 samples of pressure
  pressure = analogRead(analogPin);    // read the input pin 
  long pressure = 950 + pressure / 8.5;  //convert it to milli bars
  Serial.print("\t pressure = ");
  Serial.print(pressure);   // print the pressure
  Serial.println(" mb");
  delay(5000);   // wait 5 second before next sample

An example of my reading would be it would start at a value of say 750mb, then go 0mb..0mb then when I apply pressure using a syringe it would jump up to 1bar,But then go 0mb..0mb then 1bar etc.

Im trying to wire up and code a Honeywell gauge pressure sensor to an uno as part of my final year collage project. Does anybody have any experience with using such a pressure sensor? I have attached an image of the sensor and datasheet. Any replies would be greatly appreciated  smiley
