 | | Using LEGO active sensors
|
|
I would like to use my LEGO active light sensors with the HB. Has anyone done this without purchasing the commercial expansion board? Can anyone recommend a good way to proceed? Thanks. Jim (23 years ago, 5-Oct-01, to lugnet.robotics.handyboard)

|
|
I have recently begun using the Handyboard with the non-commercial version of IC. My PC runs Windows ME. I was unable to get IC to communicate with the HB until I booted the PC in safe mode. Are there other ways to handle this problem? Thanks. Jim (23 years ago, 5-Oct-01, to lugnet.robotics.handyboard)
