"Such is defining inputs according to architecture. If it is analog then scale accordingly."

"Thanks alot!!!!!! It worked finally. Lifesaver is what you are"

"According to this: http://arduino.cc/en/Tutorial/AnalogInputPins You should remove the line "int A6;" Because that sets up a variable A6 that will have initial value 0, so the pinMode() and analogRead() calls will attempt to operate…"

"Thanks for your help. Im going to go and solder my header pins onto the expansion ports and hopefully it will work. I will plug it into AN6. Just to confirm, this is the code I will be using:   int A6; long anVolt, cm; void setup() { …"

"In the industrial workplace I work with 0 to 10 Volts DC or a 4 to 20 ma Loop. A 4 to 20 ma loop seeks. A 0 to 10 volt references to the voltage. Understand the power to reference might be different. Personally I like a power loop. The I2C has very…"

"Maybe the "expansion ports" on the blue board? Otherwise, I would think the 3-pin headers should have Vcc and GND (standard servo pinout) "

"I was still using the Pitot tube pins (They are on the right of the board in the picture you have provided). There is GND, +5V and IN. I also posted below  "

"OK my bad I was using the wrong pins thats why my code wasn't working. I am going to go and solder on some header pins to the pins you have mentioned however where is the V+ 5V? All I can see is GND and the analog signal pins."

"Does that code actually compile? What is A0? What integer value is the variable ADC0 set to? Maybe just a typo. Which analog pin is the EZ0 is plugged into on the blue board? What does the silkscreen label next to the pin say? How is the sensor…"

"Try measuring output of sensor with a voltmeter between signal and ground...  Then measure hooked up to Arduino, measurement should be with range of sensor output..."

"I have tried using your 'hints' and i have written some code to go along with it: int ADC0; long anVolt, cm; void setup() {  Serial.begin(9600);} void loop() {  pinMode(ADC0, INPUT);  anVolt = analogRead(A0);  cm =…"

"Ok, a MaxBotics EZ0. I have played with the EZ1; same interface. It doesn't support I2C at all. It supports asynch TTL Serial, as well as Analog and pulse width timing. Let's go back to the analog interface you were pursuing. You need to…"

"It is a MaxBotix XL Maxsonar EZ MB1200. Here is the link: http://www.maxbotix.com/products/MB1200.htm Please bear with me this is my first time using this type of hardware."

"I2C sensor pin http://lmgtfy.com/?q=I2C+sensor+pin  "

"The title says I2C sensor... if your sensor speaks I2C protocol and if you've plugged it into an I2C port (SDA, SCL) then you'd need to use the Wire library to talk to it.  What sensor brand/model is it? Michael"

"This is the code I am using but need to find the pin ?????   const int anPin = ?????; long anVolt, cm; void setup(){ Serial.begin(115200);} void loop(){  pinMode(anPin, INPUT);  anVolt = analogRead(anPin);  cm = anVolt *…"
