So i have been trying to get a ultra sonic senor working and i am having no luck. i have 3 to chose from but don't know what to use or how to use them.
we have:
1. The Paralex Ping)))

2. the VEX kit one
3. Max Sonar EZ1 modle
We haven't gotten anything to give me a good value. If anyone has can they tell me what they did and tell me or show me. If you can that will be a great help to us!
