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

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...

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?

@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...

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.

@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.

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.
