| The MB design keeps ground in common, but the ground to the cpu, has an inductor in line with it, the HB also has a inductor on the ground side, I think. You might want to put an inductor on both sides of the motor, with a cap inbetween both of (...) (29 years ago, 24-Mar-96, to lugnet.robotics.handyboard)

| If I add a separate motor power to the L293's, can I keep the ground lines common? If not, what pins are motor ground? (I know pins 4,5,12, and 13 are ground) Thanks. -John (...) (29 years ago, 23-Mar-96, to lugnet.robotics.handyboard)

| | | | | Re: Driving large motors with the Handyboard
|
| There are several ways to do this. In Mobile Robots, they talk about H bridge circuits. If you are doing less than 2A use a L298 and some some clamping diodes ( these keep the driver chip from being fried when you turn the motor off). The L298 has 2 (...)

| | | | | Driving large motors with the Handyboard
|
| Hi. I'm kinda new at this. I was wondering if anyone can help me answer this question. If I wish to drive large motors with a Handyboard, I understand that I have to use an h-bridge. Will I need to know anything about PWM before attempting this (...) (29 years ago, 23-Mar-96, to lugnet.robotics.handyboard)

| I have a few suggestions, these are all things that I have seen before to help reduce noise from motors I think that the problem might be due to crap getting back to the power line... thereby causing the DS1233 to say, time to reset... - try a (...)

|
| Where on the v1.2 board do I tie into the OC2, OC3, and OC4 output lines? Is there a schematic which has all the I/O pins labeled? I need to use the OC lines to output pulse trains. Does the library software use these ports for the motor() commands? (...) (29 years ago, 23-Mar-96, to lugnet.robotics.handyboard)

| (...) I can't say that I have an explanation of why the motors would work at first and then cause problems later, but I can say that: Not all motors work with the Handy Board. In particular, motors that want to draw too much current (e.g., more than (...) (29 years ago, 22-Mar-96, to lugnet.robotics.handyboard)
