Hi

I came to the poit where I need to connect Ultrasonic sensor to the USB shield. Now thing is I decided to use this shield instead


and HC-SR04 as a range sensor.

In the original presentation slides the authjor says that the ultrasinic sensor should be connected to "digital pin 4" on Sparkfun's usb shield. Which pin is it and where is it on SParkfuns board? What are the corresponding pins on shield 2.0 board?
