(...) It depends... One solution is to let the motor float. Another and (I think) obvious solution is to gradually decrease the motor speed by calling SetMotorSpeed (or whatever you call that function) repeatedly with a decreasing speed value. Søren (26 years ago, 14-Oct-99, to lugnet.robotics)

Great solution Gary!

That is the same thing, except much easier. Plus we save donut money. However, we'd have to look at the effect of 7 volts reverse bias on the motor LED's. Plus, we'd have to make real sure not to short the bent pin 8 to the socket underneath it. (...) (26 years ago, 14-Oct-99, to lugnet.robotics.handyboard)
