Can anyone help me? I have got an arduino uno and an srf02 ultra sonic range finder see link: http://robotics.org.za/index.php?route=product/product&product_id=319
I have been following the instructions on the arduino wire library see link here: http://arduino.cc/en/Tutorial/SFRRangerReader
I have wired my sensor exactly how it says and when I connect my arduino to power the red light flashes on the sensor so I know it is getting power. But when I upload the code the sensor does not feed back numbers into my serial monitor. I can't seem to decipher the code, can anyone help, is there something which i have to add in in order to make it feed back?
I am sitting with everything in front of me so if anyone is to hand this evening I would be very grateful!
