The final tests and last problems with sonars

The exhibition stats in just one week, and the last final tests are being done, together with all the polishing of the setup. Angles are being covered with foam to avoid people breaking their head, cables are being routed on the ceiling and in the corners, and covered with white tape.

The sound is great, exactly how we envisioned it, thanks to our sound teacher Patrick, also for lending us the sub-woofer.

The only problem to be solved is still the sonars not getting a stable distance reading: I’ll have to try and change the way sonars are triggered, and instead of relying on the automatic daisy-chaining (as MaxBotix suggests, and apparently doesn’t work) I’ll try to trigger the readings directly from the Arduino.

  1. Simonech,

    I have reviewed your blog and comments regarding the chaining methods. I am not sure what issue you may have been experiencing, as many user successfully use one of our chaining methods for multiple ultrasonic sensor applications. I would be glad to work with you to help troubleshoot the setup. Please feel free to email me at scott@maxbotix.com so I may help troubleshoot the issue.

    Best regards,

  2. Simonech,

    I have been following your work and it is very cool. I just wanted to let you know we recently release a new series of sensors that makes proximity detection and independent multi sensor use easy. The LV-ProxSonar-EZ series of sensor can operate as many as 15 sensors in a single environment without chaining. The sensor is designed with a logical high or low output on pin 2 when an object is detected within the trigger distance. You can click this link for more details about the sensors http://maxbotix.com/Ultrasonic_Sensors/Ultrasonic_Proximity_Sensor.htm.

    If you have any questions, please don’t hesitate to email me.
