  Re: 5VDC Voltage Regulation
 
(...) OK. What I was thinking of was that if a current flows through a coil, that be a relay, transformer or motor, the current can't change at an instant. If you break the circuit current will keep running through the coil for a short time. This (...) (25 years ago, 28-Sep-99, to lugnet.robotics)

(...) You can't have the diodes on the motor because it goes in both directions. If you put a diode out there, you would have a dead short in one of the directions. Such things need to be built into the H-bridge, not the motor leads. So, I seriously (...) (25 years ago, 28-Sep-99, to lugnet.robotics)
