We are using the expansion board libraries to drive the lego rotaion sensor and seem to be getting funny output to the handy board. We hooked up the sensor to the oscilloscope and we can see the voltage transitions on the screen, but the Handy (...) (24 years ago, 26-Feb-01, to lugnet.robotics.handyboard)

Hi everyone, I'm trying to hook up a moisture sensor to the HB but having some errors. These are resistive type sensors so I have it connected to the grnd and signal on the HB of the analog ports. After connecting to the HB, at the C prompt I tried (...) (24 years ago, 23-Feb-01, to lugnet.robotics.handyboard)

Hi. I am building a mobile robot, which should operate during days continued in external enviroments. For this reason I need to replace the voltage adapter of my HB for Lead Acid batteries. I plan to use some Lead Acid batteries like primary feeding (...) (24 years ago, 20-Feb-01, to lugnet.robotics.handyboard)

(...) Hi Andy, we did it the way you described, but with a 6.270 board (little brother of handy-board). We earned performance on 6.270 with it, because the only thing we had to do is to parse the string received from serial port. We attached a (...)

Thanks for the insight, I am sorry that I did not mention the main controller would be a Handyboard (implied though due to the news group). This is still a good point and has given me a lot to think about. The slave controller would continue until (...) (24 years ago, 16-Feb-01, to lugnet.robotics.handyboard)

The advantage of distributed processing is that you can take a sometimes considerable load off the main MCU. Consider a speed regulator: a sensor is needed to continuously monitor the speed at which the wheels are turning and adjustments in motor (...)

I have noticed low cost PICs (such as OOPic) that are capable of controlling (and getting useful data out of) devices like the Polaroid sonar rangefinder and other devices. Is there a benefit in delegating processing tasks such as this to a (...) (24 years ago, 16-Feb-01, to lugnet.robotics.handyboard)

Hi from France ! I have assembled a Handy Board that works well with the original 9.6 V battery pack, but I would now use a separate power source with bigger motors to have more torque (I use a 7.2 V propulsion pack, with a H-bridge system). Since (...) (24 years ago, 15-Feb-01, to lugnet.robotics.handyboard)
