Im using the ultrasonic range finder for the first time. There was some confusion at first but I got a successful test out of it. So when I started actually writing the code for it to move I kept getting “Ultrasonic Interrupt port 8 is out of range”. I originally had the output on digital 1 and input on digital 11 which worked on the test. So when I kept getting that error I switched from 11 to 8. At this point im lost, can anyone help?
Check and see if your getting an error on the terminal window. Try the ultrasonic sample and see if your sensor works. Open -> Samples
