 | | Re: Using low voltage motors
|
| In your message you said: (...) What do you mean, "from the 20V range"? the HB supplies about 8 to 9v to its motor outs. a 30 ohm resistor would be about right for the 200mA current level. The resistor would drop 6v leaving about 2 for the motors. (...) (28 years ago, 23-Apr-96, to lugnet.robotics.handyboard)

|
| Today, for the first time, I decided to actually try out the new version of IC on my new Pentium, running Win 95. To make a long story short, it doesn't work. Why? Because I've got two devices, my mouse and my internal modem, which are always (...) (28 years ago, 23-Apr-96, to lugnet.robotics.handyboard)
| | | | | Using low voltage motors
|
| I'm using two low voltage motors that come attached to a really cool gear box. Or rather I want to use these motors. Each seems to work best at about 2.0 V. When running they draw about 200 mA. I tried running them in series with a 40 Ohm resistor (...) (28 years ago, 23-Apr-96, to lugnet.robotics.handyboard)

|
| (...) Each sensor "connector" is a column of pins in the following format, where "X" denotes a pin position: X X X So, if you look at the lower edge of the HB, you have 16 positions in a bank of 9 and 7: XXX...XXX XXXXXXX XXX...XXX XXXXXXX XXX...XXX (...)

| (...) Check out a diaram that I uploaded to cher. It's in postscript as well as GIF format. It has all of this suff on it (and more). I made it out of frustration while I was working on my HB! It's at ftp://cher.media.mit...b/schmalz/ as well as a (...) (28 years ago, 22-Apr-96, to lugnet.robotics.handyboard)

| Go to the Handy Board web page and follow the links to the schematic diagrams. These will probably answer most of your questions. I have to look them up myself, every now and then. Larry (...) (28 years ago, 22-Apr-96, to lugnet.robotics.handyboard)

| (...) You might want to check the handy board web site, at (URL) as it gives a diagram of the function of each connector on the board. Also, there's a document about interfacing sensors to the handy board which will give you a pretty good idea of (...) (28 years ago, 22-Apr-96, to lugnet.robotics.handyboard)
