Maxbotix Question

I know that this sounds crazy, but . .

I removed six working maxbotix EZ0s from the LEAF robot that I disassembled. They were all working.

I wired them as directed (no brainer.)

None of them worked. I hooked them to the ADC ports. I tried all ports and all sensors.

I tried several ways of wiring them. No soap.

I even tried them on Digital.

I am beginning to think my ADC ports are not working.

Thanks!

ARC Pro is your passport to a world of endless possibilities in robot programming, waiting for you to explore.

The next logical thing to do is test your analog ports... Surely you have a sharp IR detector lying around to test them with? Maybe a potentiometer too?.... It is highly unlikely you have blown the analog ports... My guess is that you are still confused for some reason on how to use the EZ sensors.... Plugging them into the analog ports is just as easy as plugging in the sharp IR sensor.... 3 wires Mel that's all...

#2  

I had about 12 of the sharp sensors. But, I have threw them all away one at a time after testing them and they not working.

I need to regroup.

#3  

Look at the back of the EZ0..... put your glasses on... follow the steps below exactly...

  1. See the pin that is labelled GND? Plug that into the ground pin on adc0
  2. See the next pin +5? Plug that into the 5V pin on port adc0
  3. See the pin labeled AN? Plug that into the last open analog pin on adc0

Open the read analog value control in ARC.... set it for analog port adc0... Now read the values

#4  

How did you possibly ruin 12 Sharp IR? I still have some that I used 15years ago when I was using the basic stamp that still work perfectly.... You know you probably threw out 12 perfectly good IR sensors....

Yes, good idea re-group.... Step back and think before you wire things up.... Wiring electronics seems to give you a lot of grief.... Just take your time and triple check your connections before applying power....

  1. Do you have a potentiometer? or any other analog device?
  2. Are you sure your ezb3 is connected to ARC? A flashing LED on your ezb means it is not connected to ARC
#7  

Cycle the power on your ezb3 and then re-connect to ARC....

I have 4 MaxBotix EZ1's, all of which work fine in analog mode...

I will do this as soon as I can. My wife is having some health issues and is taking up a lot of my time.

I should have a pot in my toolbox.

thanks, Mel
