Hi, Just a quick question...What would be most effective ? An array of sensors (IR or sonar), or a single sensor on a continuously rotating base (assume 1 rotation every 2 secs...) ? Could someone here explain me the main functional differences of (...) (25 years ago, 9-Apr-99, to lugnet.robotics.handyboard)

The problem I have isn't programming the HC11. I picked that up with no problem by spending a day reading Motorola's reference manual (AKA the pink book - kindly provide free by Motorola via their web page). I've got a software background, and while (...) (25 years ago, 8-Apr-99, to lugnet.robotics.handyboard)

Hello all- I am using my Handy Board on a robot. My team and and I thought it would be really cool if we could get it to play music while it is moving. Is there a way to do this? In my testing it seems that it only does one or the other. If anyone (...) (25 years ago, 8-Apr-99, to lugnet.robotics.handyboard)

I've taken a look at Chuck's LCD code, and I agree that it's the best I've come across. I spent last weekend studying how to program the HB in assembly. There is a woeful lack of documentation for it. There is plenty of docs on programming in IC, (...) (25 years ago, 8-Apr-99, to lugnet.robotics.handyboard)
