|

1) If you have a serial tower, there is no reason I can think of to purchase the USB tower. If you use a USB tower, then you will need the USB support that Robolab 2.5 provides. 2) The hardware differences between the 1.0, 1.5, and 2.0 bricks are (...)

I suspect this is due to the fact that the first sample from the sensor is actually being obtained while the sensor's reservoir capacitor is still charging. Why don't you try a simple test, actually two tests; 1. Initialise as passive sensor Wait 1 (...) (23 years ago, 27-Sep-01, to lugnet.robotics.rcx.java)

| | Light sensor initialization time?

Hellow! Here a little fact: the first reading on the light sensor _just_ after you have activated it is too high. It seems like one has to wait a little after activating the sensor. The following program shows it rather nicely: ____START OF CODE____ (...) (23 years ago, 27-Sep-01, to lugnet.robotics.rcx.java)
