 | | Strange question
|
| Has anyone here used Electronic Workbench ? I've got a copy but it doesn't have schematics/models for the darlingtons (TIP120, 125, etc) I'm looking for spice models and ideally an symbol library. (yes it is for simulating various power control (...) (28 years ago, 5-Jun-96, to lugnet.robotics.handyboard)

|
| (...) Use a voltage divider (two resistors) to map the battery voltage to a 0 - 5v signal for the A/D converter. Depending on how much current your motors draw, you can put a .1 ohm precision resistor in series with the motor and measure the voltage (...) (28 years ago, 4-Jun-96, to lugnet.robotics.handyboard)

| I'm interested in building a voltage monitor circuit for my robot's 6V battery, and a current monitor circuit for the motors. Is there an easy way to do this, with reasonable accuracy? I'd like to interface both of them to the analog sensors on the (...) (28 years ago, 4-Jun-96, to lugnet.robotics.handyboard)

| The PWR light isn't really an indicator of power. It's actually hooked up to the 6811's serial transmit line, so it's supposed to flash when the 6811 is talking serial. the BATT light should always blink when the board is first switched on. It also (...) (28 years ago, 4-Jun-96, to lugnet.robotics.handyboard)

| Cris, I just built my HB last week, I can offer these comments.. The green power LED should flash while you are loading the board through the serial port. Actually, it's more of a flicker, it's just an indicator of serial activity. As far as the (...) (28 years ago, 4-Jun-96, to lugnet.robotics.handyboard)
