On the EZB V4 digital pins, what color is VCC Pin, Output/Input pin, and Gnd Pin? Is it White(or Blue), Red, Black?
Upgrade to ARC Pro

Are you saying the ultrasonic sensor I bought with the V3 will not work on the V4 without a special cable
Also, now my robot won't even power up. While measuring pin voltage a made a spark.
You probably just blew a fuse. There are two. A self resetting one in the EZ-B itself. Just give it some time and see if it turns back on. If not, then check the replaceable fuse in the Roli body. See http://www.ez-robot.com/Tutorials/Lesson/47 for instructions.
Assuming it is OK and comes back up from one of those, I can help you out with the sensor.
You have a 3D printer, and I need some small parts. If you print me 2 of the small bits and one of the large bits for a rotation servo, I will send you an unopened HC-SR04 and an L7805 voltage regulator you can solder onto a cable for the HC-SR04.
Send me your snail mail address in email (my email address is in my profile) and I'll reply with mine.
That sounds great. I have some of the parts printed up already. Show me which parts you need printed.

Can you confirm my schematic....
I've killed two ping sensors due to my mistake trying to do this without the voltage regulator...
I'll look it up in the morning.
Happy New Year
Thanks so much. I'll wire that up and try it out. One question I have is the output pin regulated to 5v in the ezb?
I'll get your parts printed.
