Hi there, I tried finding the electrical schematics for the PING))) and HC-SR04 ultrasonic sensors (the schematics of the boards themselves, not just wiring to an Arduino) but I couldn't locate any. Can anyone point me in the right direction? Thanks!

I just put "HC-SR04 schematic" into Google, and got results.
What did you do wrong?
