The port nearest to the ethernet port is a USB On-the-Go port, while the other two are ordinary High-speed USB ports. Some webcams and USB Hubs have poor compatibility with USB On-the-Go, so it's recommended that you use one of the normal ports for these purposes.

Yes, the problem is DistanceSensor (with capital D and S) is the name of the data type of our distance sensors in the phidget22 library. Earlier in your program there should be a line like: DistanceSensor insertNameHere = new DistanceSensor You need to call insertNameHere.Distance.toString() for wha...

What error message do you get when your program fails?

What kind of temperature sensor is it? Are you able to see it when you open the Phidget Control Panel? Your program only checks if the Phidget is attached once- it's possible the "Attached" flag hasn't been set yet in the small time between Open() completing and checking the attached status.

You will need to update your phidget22 python module to a newer version, since DataRate was added more recently than 2020. That being said, you can just use DataInterval instead, which uses milliseconds between samples instead of samples per second. DataRate was added because we're starting to come ...

Phidget channels can only be opened in one program or process at any given time, so it seems like for some reason your python script is still running after it closes. You can test this by using the ps command before and after running the python script for the first time.

If the relay can be activated by a 5V DC output, then the InterfaceKit 8/8/8 can activate it. Go to the product page for the 1018 PhidgetInterfaceKit 8/8/8 and go to the code samples tab. Select Java from the language drop-down and make sure one of the Digital Output boxes are checked. It will gener...

How far apart are the readers going to be? You can use the 1024 - PhidgetRFID read/write at each of the locations, but it has to connect via USB to a computer of some kind (PC, laptop, SBC, raspberry pi, etc). USB cables can only reach about 5 meters, so you may need multiple computers if the locati...

What sensor are you using? Is it the 1108? If so, there is no code sample specifically for it because it's simply a 0-5V sensor. You can go to the product page for the 1108 and click on the code samples tab and select the device you're using to read the 1108 (e.g. 1018_3, HUB0001) to see how that de...

It's hard to know for sure what happened, but hopefully it was just an issue with the connection of one of the wires or something. If it happens again, try to capture any sensor data or logs you can, and that will help us figure out what could be causing it.
