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

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...

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.

i have two adresses back 0xa2 and front 0xa4,the front dont work. i try a new rgb and that one works but again same led as the back side.

indeed am paniking.am working allreddy the hole day.

rr i try the radar separt and it same error.

steve

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

@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.

I solved the rgb problem.am uplouding the video now.one rgb had an diff adres now i have tailights and face diff.i tested the wires first from the rgb with new one still same ,then i used a new rgb. Works but not diff.

ok the rgb problem solved.one rgb had diff adres.

the radar works now.it was a bad rgb.i tested with other ezbv4 same error. so roli is complete .hpoe i get another rgb block here in belgium. i try 0xa0/0xa2/0xa4/0xa6(worked one time)0xa8 i gave the points to RR he said to try the rgb alone nothing els connected.

thanks all
