Gole I think Massimo is in Sweden and I am in Canada, near the pacific, so here is part two of your international answer! As i am planning to control the l from the arduino board, can i just use 5V output from that to power the l or do you suggest an external power supply using the?? Any idea why that might be??

Any idea why that might be?? The 5v cominoug from arduino when connected to the USB are supplied from the computer. Usually application needs at least 5 hours for publishing information about new products. Hi I made some stepper motor drivers with the L and L five years ago, and they still work great!
Does this mean that I need to use some capacitors with the or are they included inside the?? Another reason for separating the supplies is to prevent noise from getting back into the microprocessor. To avoid destroying the motors, the current through the windings is monitored and power is cut off when the current reaches a critical level. Supply voltage drops are bad news for microprocessors!

I think Massimo is in Sweden and I am in Canada, near the pacific, so here is part two of your international answer! Please, try again later. If you want to control a unipolar stepper, you can use the l with the ULNB In all cases, you will need a few extra components to complete the circuit. So, now I have some questions for you! If you do want the chopper drive The motor takes ratasheet step for each pulse sent from the arduino board. Daniel suggested Schottky diodes. If i do need to use the with some external capacitors, how do I wire it up??
In terms of the 12V motor supply and the clean 5v supply, the answer lies with the motor. Basically any Schottky diode with a 50V voltage rating and a 2 or 3 amp current rating will do the trick. For the regulator you need the old standby circuit for the I can only find basic AC adapters at maximum 1. Would you recommend another IC or is it cheaper to use seperate diodes??
