PING ))) eco problems
Hi, I wonder why the eco pulse I receive from the sensor·is only 0.5 volts, I·had connect the signal to my micro MC68HC908GP32, I am connecting the PING))) to 5 volts as the data sheet indicates, but something must be wrong, because the eco pulso must be 5 volts right?

1) Somehow the scope is set wrong (most likely) and you really do have a 5V pulse.
2) There's something odd about how you've connected everything together. You'll have to post a diagram.
3) The PING))) is somehow damaged or there's a error in its manufacture.
Logic like the PING))) rarely fails with a low output voltage. It either works or you get nothing.
Maybe the microcontroller has a problem or is programmed incorrectly so it's shorting out the PING)))'s output.
