You did a great job measuring that distance my dear Ping))). Until I stupidly shorted you out. Or maybe it was you I2C Logic Level Converter. Anyway. You both did the thing I wanted. Only you did it in Python, not Java. You were my best reason to try to learn Python. Now you are gone.
I was just going to switch out that stupid ground cable and I touched the red voltage line. I my hurry I didn't turn off the Raspberry Pi. The Raspberry immediately shut off to protect itself and was then seemingly feeling fine. I don't know about you my dear Pin number 7. But you read noise pretty well anyway, maybe I can use you as a Random generator.
