Hi Nomad, Do you have an Ultrasonic version 2 sensor with 3 wires? If that is the case the trigger and echo ports will need to be configured to the same port (ex: both configured to D21) For the I2C address, I don't believe it's case sensitive (lowercase 'a' or uppercase 'A' shouldn't matter) but I will look into it.

hi jeremie the back rgb works on 0xa2.the front i changed into 0xa4 i see blue color, but when trying to use the rgb ,the ezbv4 chut down,disconnect. the ping sensor is with 4 wires black/red/green/white,all set like in tutorial. but when using the radar i see ubove red line not in the green part, so i gess it dont detect objects. thanks

Quote:the ping sensor is with 4 wires black/red/green/white,all set like in tutorial. The old version of the ping (4 wires) needs a 5V voltage regulator... Are you using a 5v voltage regulator with your ping? If not you will destroy your ping...

hi RR yes there is standard a 5 v regulator.i only use ez robots parts. thanks

Did you check to see if your ping actually works without anything else hooked up or in your project? Meaning just the ping and a distance sensor control?

if you see my last foto ubove you see a red line.doesn this mean the ping woorks?

@nomad If the ping is working, you will see the values move (you're picture says 255). If you move your hand closer to the ping, these numbers will go down. I did notice in your pictures of the radar control that the "Pause" box has a tick in it. You have to click on the tick to remove it for your ping sensor to pick up readings...

DJ Sures · Answer

If anyone noticed - he's not actually connected to the EZ-B. Look at the debug window, it's disconnected. Most likely because the EZ-B locked up due to an invalid RGB i2c configuration. Nomad, you're in panic mode and not paying attention Tackle one thing at a time... first, I believe that you're attempting to configure the RGB Eyes to have a different i2c port? Well, firstly... you can only have 1 i2c device per address. So you cannot connected 2 i2c devices with the same address.

steve uncheck the box,then the radar starts.it does move.only i dont see objects. in the green field

Steve G · Answer

@Nomad

Do the distance numbers change when you move objects in front of the sensor? The number saying "255" on the bottom of the radar control (255 is maximum, 1 in minimum). The closer the object gets to the sensor, the number should come down.

Nomad 6R · Answer

no the number stays at 255 for the rgb i notest when making a vision only one side works.

nomad - let's tackle one at at time Also, take a short break - sometimes stepping away from a problem helps.
