| | Re: Handyboard, Servo motors
|
|
Hi, You can check the link of how to hook up servo (look for by Gary Livick's contribution): (URL) will be easy if you have HB Expansion board since you just connect the servo directly into it. The servo library is already there for the expansion (...) (22 years ago, 20-Feb-02, to lugnet.robotics.handyboard)

| | Handyboard, Servo motors
|

I'm working on some research with the Handyboard, and I don't know too much about programming it yet. I've figured out how to work the DC motors but not the servo motors, I think I've attached the pins correctly to the wires on the servo motor but I (...)

Hi. I am putting together a Handyboard and have been having success until it came time to test the bootstrap mode. The interface board's voltages check out and it blinks as it attempts to download. I am using an E1 and the Mac 6811 downloader. The E (...) (22 years ago, 9-Feb-02, to lugnet.robotics.handyboard)

| | Re: Sensor Connector
|
|
The LEGO shaft encoder and light sensor are active sensors that need a special circuit. The Expansion Board for the HB provides this ckt and the requisite drivers. Your simplest path to using these with the HB is to get an Exp Bd. Barring that, you (...) (22 years ago, 7-Feb-02, to lugnet.robotics.handyboard)

Another question: How can I get the handy board to read from the lego rotation sensor and the lego light sensor? I can get the touch (...) (22 years ago, 7-Feb-02, to lugnet.robotics.handyboard)

I've bought some lego electric plates (part 5037) from lego.com, and they seem to be withstanding the heat of a soldering iorn quite well (that was my fear... that I would turn them into bubbling messes). Actually they're holding up better than the (...) (22 years ago, 6-Feb-02, to lugnet.robotics.handyboard)
