I think Massimo is in Sweden and I am in Canada, near the pacific, so here is part two of your international answer!
I don’t understand how to select the appropriate one. The driver will draw such large currents that connecting it’s power suply to the Arduino’s risks passing the power supply transients back to the Arduino. Thanks for helping out a slow learning electronics geek wanabe! If you can answer any of these questions, I would be very grateful! Also, i’m still wondering Is there some other setup which I should be investigating??

We map away wrong codes or sometimes logistic variants. I’m getting closer to actually trying to build this thing! It includes two PWM chopper circuits to regulate the current in the motor windings. Anyway motors unless tiny should not be powered from the regulated 5V supply but should use the unregulated voltage supplied to the board this usually floats between 7.
I have a few simple questions Daniel Massimo is in milanthe capital of design I subscribe to everything you wrote in the post. I’m new to electronics.
Use a separate supply. I don’t yet understand how to implement the chopper drive properly. I would like to compile circuit designs using the l to control bipolar and unipolar steppers, with and without chopper control. How do I know when it is adjusted right??

Basically any Schottky diode with a 50V voltage rating and a satasheet or 3 amp current rating will do the trick. If you don’t want the chopper drive The general rules are: I will now start trying some circuits, i’ll post when I get one working.
The l can create the control signals for bipolar, unipolar and variable reluctance stepper motors. Can anybody explain how to connect up this pin?? 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 ?? This technique is known as “chopper drive” and it allows the motor to increase its top speed. I just checked the farnell site for the l and it is listed as no longer stocked?

The 5v cominoug from arduino when connected to the USB are supplied from the computer. What I don’t understand is Motors and inductors put out a large voltage spike when their fields collapse, and you don’t want this to get back into the microprocessor supply, so you use a separate supply. If you do want the chopper drive I hooked some quite large steppers up to it and it never failed. When a stepper motor turns on, it draws large amounts of current into its windings.
