is it possible to tell me the chip of receiver? and the laser is I put  500mw laser diode I think is good.  I'd like to find how much is the cost of receiver

thanks all,

   I'd like to measure distance 150 meter or more.

thanks,

   have you a example of this (with camera)?

Hi all,

    I' like to measure distance but the ultrasonic transceiver is not long range. Someone know how can I make a long rangefinder? I think the only one way is that, if I made a rangefinder with laser on transmitter and receiver ultrasonic sensor.

     how can I convert the character-string function into number dec? I know a function String(value, DEC); Moreover, I write you my code

   
Code:
void loop()
{
 
  LcdClear();
  gotoXY(0, 2);
  distance = ultrasonic.Ranging(CM);
 
  LcdCharacter(ultrasonic.Ranging(CM));  // this functhion give me the character no decade numder !!!

  LcdString("cm");
   
  delay(3500);
}


I would like this http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1272177425

furthermore, I believe the solution is in this function,

Code:
void LcdWrite(byte dc, byte data)
{
  digitalWrite(PIN_DC, dc);
  digitalWrite(PIN_SCE, LOW);
  shiftOut(PIN_SDIN, PIN_SCLK, MSBFIRST, data);
  digitalWrite(PIN_SCE, HIGH);
}
[code]

how can I shiftout() DEC number and no byte data???

   hello,

   I've the nokia lcd 5110 module. So, I must print the decade numbers from convert Distance in cm from my HC-SR04 module. Have you idea how I can do that? Because, the PCD8544 library haves only functions which they print characters.

   Hello,
  
  how can I see inverse data ? I can do that with this  "   LcdWrite( LCD_CMD, 0x0D );  // LCD in normal mode. 0x0d for inverse"

  No, I have an arduino mega only, it need a nano?

  Is it right this change,

   /*
    unsigned char s = RADIO_RSSI(n);
    */
   
    unsigned char s = analogRead(n);

to read from analog "PWM pin 2" -zero interrupt a wave???

hello,

  I'd like you to describe the operational buttons. Is it two? Is it first interrupt "PWM pin2" is zero interrupt and on this pin connect the input wave, receive signal? Furthermore, the "MODECOUNT 5" is digital pin 5? on this pin connect the switch button?

 I can't run sketch in the processing.exe environment, which folder to put my sketch and libraries? Automatically, the processing.exe  it have created a folder in my doccuments with name called processing.  smiley-roll

Often the processing environment is used for displaying graphs etc on a PC. Check - www.processing.org -


I can't open the processing.exe

ok I open it !!!! I put it in C:\

hello,

 Have some a project spectrum analyzer which it read serial port on arduino board (I have an arduino Mega_1280  smiley-grin) and it watch on pc application the analog value from arduno analog port? read voltage or frequency?

   I have this one
http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1285785582

   and I would like one like this

sorry for my english
