 | | Re: Interfacing GP2D02 with handyboard
|
|
If you are not conversant in assembly, it will be difficult to obtain code for each individual digital port unless you get someone to write it for you specifically. However, if you switch to GP2D12 sensors, and remove the pullup resistors on the (...) (25 years ago, 10-Jan-00, to lugnet.robotics.handyboard)

I am trying make a robot that communicates with a computer program build in borland C. can i use the serial port of the Handy Board? how do i send and receive commands or messages to and from the HB through my boland C program, using this serial (...)

I believe someone asked a similiar question to this but I didn't get an answer (I don't think). Question relating to the HB expansion board and servo control (or lack of same). I can control standard servos (S148, 3003 etc.) just fine, they run as (...) (25 years ago, 10-Jan-00, to lugnet.robotics.handyboard)

| | Re: LEGO sensor
|

just to be clear, there are two types of LEGO sensor: active and passive: * passive -- touch sensor, temperature sensor. * active -- light sensor, rotation sensor (aka shaft encoder, angle sensor) without expansion board, the HB can only deal with (...)

The LEGO sensors and the RCX are the same thing. The standard Handy Board (without an expansion board) can handle all of the passive LEGO sensors such as the touch and rotation sensors. The expansion board is needed to use the active sensors such as (...) (25 years ago, 9-Jan-00, to lugnet.robotics.handyboard)

| | Re: Higher voltage for HB battery
|

I find that the ideal solution to this situation is to build a power system for the robot. Maxim, Linear Technology, and National each make very easy to use switching regulators that can provide highly efficient DC to DC conversion. Building a (...)

Some of the expansion board kits (all? sorry, haven't been paying much attention to the extension boards yet) mention that they have slots for LEGO style sensors. Does this mean the sensors they use on their RCX/Mindstorms stuff? What's the (...) (25 years ago, 9-Jan-00, to lugnet.robotics.handyboard)

| | Higher voltage for HB battery
|
|
I would like to know whether the HB can be used with a 12 V (ten AA cell) NiCd battery instead of the standard 9.6 V (eight AA cell) NiCd battery. Specifically, (1) Would the HB be damaged by the higher voltage, (2) Would the HB function properly (...) (25 years ago, 9-Jan-00, to lugnet.robotics.handyboard)
