Help Please I have added the ultrasonic radar to my project. I tested it with the 3 different controls and can not get a full display of the scan. It shows about 55 degrees of scan and the rest of the display is black. I know the scan starts at some point below the bottom left hand side of the screen by watching the "servo" info at the bottom of the screen. The display starts to show the scan line at 40 and quits at 100. Otherwise it is working OK.
Development kit It is shipped with voltage regulator connected to ultrasonic sensor , pls check "out " connection of regulator is connected to ultrasonic sensor. Found on opening two development kits both were incorrectly connected.
@Bravia I think the OP is using an EZB3 so no need for a voltage regulator. Unlike the EZB4 the ezb3 regulates it's digital and analog pins to 5V with built in 5V regulator...
The most recent Ultrasonic Distance Sensor only uses one connector (not 4 wires like previous version). See photo of Ultrasonic Distance Sensor as it only uses one digital port and has built-in voltage regulator within the plastic housing.
@DJ....
I saw that, nice. Adding a built in v-reg is a serious bonus... Going to be adding a few of those pings to my next ez robot orderTHANKS EVERYONE. I do have JD and therefore I have a V4. I just wanted to continue using the V3 and add the ultrasonic sensor but obviously it is out of the question. I will return the V3 for the credit and purchase a comm 2.
How exactly do I check if the V4 in my JD should be upgraded?
There really is no need to upgrade the V4 in your JD. The upgrade board sold in the EZ store is mostly for do it yourself builders that really put a demand on the comm connection and their applacations are really doing lots of stuff. Your JD should run just fine using the EZB it came with. Of course it wont hurtto upgrade but I don't think you'll notice any differance.
Thanks.
