tnx replay but i didn't get what i wanted!
3  Using Arduino / Project Guidance / How to make a quadcopter! on: April 15, 2013, 08:28:00 am
hello there
i want to make a quad-copter starting from zero, i have some experience in electronic and i'm good at Arduino.
i don't what to buy and where to buy the materials?
can anyone help me?
thanks smiley
4  Topics / Device Hacking / how can i run arduino IDE on android? on: February 20, 2013, 11:36:07 am
hello
i want to upload code directly from android to arduino?
can they talk to each other
i saw some post that talked about running Arduino IDE in android by linux version
thanks for replay
best regards

9  Using Arduino / Sensors / Problem with connecting and reading value from MQ - 4 to arduino on: February 05, 2013, 08:15:00 am
I got a  MQ - 4 sensor and breakout board,
the data sheet of the breakout board is like that:
GND -------------- gnd of arduino
B1 ---------------- ???????
H1----------------????????
A1 ----------------?????????
Please if you know which pin i should connect them please replay
i searched internet and read the datasheet but i couldn't get any information for that pins.
and i got this code online for reading value:
Code:
int sensorValue;

void setup()
{
  Serial.begin(9600);      // sets the serial port to 9600
}

void loop()
{
  sensorValue = analogRead(0);       // read analog input pin 0
  Serial.println(sensorValue, DEC);  // prints the value read
  delay(100);                        // wait 100ms for next reading
}
best regards

thanks for the idea but i can't do it?

li didn't understand . can u make it clearly?

Code:
if (value > 68 && value < 112) {
    Serial.println("E");
  }
    if (value > 23 && value < 67) {
    Serial.println("NE");
  }
   if (value > 338 && value < 22) {
    Serial.println("N");
  }
   if (value > 293 && value < 337) {
    Serial.println("NW");
  }
   if (value > 248 && value < 292) {
    Serial.println("W");
  }
   if (value > 202 && value < 247) {
    Serial.println("SW");
  }
   if (value > 158 && value < 201) {
    Serial.println("S");
  }
   if (value > 113 && value < 157) {
    Serial.println("SE");
  }
And i get
Code:
