This is a relatively obscure fact about LabPro.
Channel 4 is different from the other three analog channels because CH4 is used for the analog output feature of LabPro. CH4 will read any sensor you plug into it correctly with the following limita...

In June 2023, the Web VPython Go Direct library was updated. One change to the library was to return a 'None' value from gdx.read() when a new sensor value is not yet available. The previous library did not return a 'None'; instead, it sent duplicat...

When reporting the resolution of a sensor, we are really reporting the smallest step size that a chosen interface can report from the sensor in question without seeing bit noise. This is not a measure of sensor accuracy.
Different interfaces use ...
In general, older sensors from ULIs and Serial Boxes can be used with new interfaces using an adapter. The newer style sensors have a feature called Auto ID, and our software instantly recognizes them when connected. Older sensors do not have this fe...
