Welcome Please help is simple

Hello
I'm a new member like Arduino programming, but I want a little help and is only a simple modification to the code

Simple graduation project

On experience Hahz but I want to add a simple matter
CODE is a resistance measurement circuit
But I want to add the code is simple
Is when they exceed the measured resistance value ratio of 300 to 400, it will light the LED on the output pin No. 11 to alert

And when they are valued in a ratio of 260 to 290 LED lights on the way out the pin No. 5 to alert

Thank you
This is the code you want to add the amendment it
:smiley-roll-blue:

This is the code

Code: [Select]

/*
 Analog input, analog output, serial output

Reads an analog input pin, maps the result to a range from 0 to 255
and uses the result to set the pulsewidth modulation (PWM) of an output pin.
Also prints the results to the serial monitor.

The circuit:
* potentiometer connected to analog pin 0.
  Center pin of the potentiometer goes to the analog pin.
  side pins of the potentiometer go to +5V and ground
* LED connected from digital pin 9 to ground

Moderator edit: Code tags. Again.   AWOL

Use code tags. And do your own homework. Please ask a *specific* question, not just "write this code for me!"

EMAD

Sorry, but I did not understand what you mean  :smiley-roll-blue:
I want to help because I beginner in programming Arduino
Thank you

Your other post got deleted> Read this: http://forum.arduino.cc/index.php?topic=97455.0

And we will not just "ammend" your code to do your assignment for you.

You need to ask a specific question like:
"How do I tell whether a value is between two limits? I tried this...and it does not work."

Where the ... is the code you used in an attempt at solving the problem.

Hint:
you need an if () statement.

EMAD

Yes, I want to if

Yes, I tried to add on to carry out the universe compared to the value of resistance and giving is directed by the pin No. 11
LED to illuminate
If the value is between 300 to 400

And the other case

Director glows 5 Pin number if the resistance value is 260 to 290

The code you want to do is start the process of comparing (resolutions) If


:smiley-roll-blue:Thank you

What you want is pretty simple:
Code: [Select]

if ((sensorRead >=300 ) && (sensorRead<=400) ){
// do something
}
if ((sensorRead >=260 ) && (sensorRead<=290) ){
// do something different

How do you know?
Please use code tags when posting code.

SensorRead and SensorValue are two different variables.
