First, I wish to greet all the members of this forum and that these words are worth as presentation.
And, of course, I want to ask a little question I have:
void loop()
{
digitalWrite(12, HIGH);
digitalWrite(paso, HIGH);
delay(100);
digitalWrite(12, LOW);
digitalWrite(paso, LOW);
delay(100);
}
The pin 12 is to see me in a LED each program cycle ...
Awaiting your instructions ...
A greeting.
P.D.: Sorry for the English, is the translator of google.
First of all thanks for answering so quickly.
It is like putting the images in the message. When stepping motor feed him with a 12v source. and noticed that the engine responds something, to play with their coils 12v directly. The scheme is the one in the link in the section where it says "using the driver". What I have is not the 100uF capacitor in the motor supply terminals.
Initializations terminals "sleep" and "reset" for I have put in place instead of directly to +5 v, inicializaras with arduino so you can "play" with the settings to see if it must be HIGH or LOW
I'm playing with drv8825 and I have the same problems. The DRV8825 doesn't work. I use 12V power supply, the wiring is the same you have put in place.
I connected with Arduino only one gnd, because in the driver the gnd pins are already connected.
May be is the capacitor? I don't think because in the manual is written that it is used only to avoid destructive LC voltage spikes.
The mistery is not ended...
GND all the sack of the same power supply generates +5, -5, 0 (GND), +12 and-12V. The LED connected to pin 12 of arduino I use testing as well as I tried to exit the arduino variety STEP.
