Control Stepper Motor using Arduino Uno

[syahrani84]

i have using Aruino Uno and Enhanced 2A Stepper Motor Driver to control Minebea Stepping Motor but failed...i have refered all the circuit diagram and sample sketch Arduino provide by Cytron..can u explain to me why this happen??

Hi,

your arduino is sucessfully programmed?
all the connections are done properly?
can u upload photo of your circuit?

i'm using Sample Source Code - Arduino (Nov2011) for my programmed...the programmed was uploading successfully but when i try to load data by using Serial monitor there is still no response...kindly please help me to solve this problem..i also upload photo of my circuit as your requested..tq

Where is the power to the motor?

i just follow schematic diagram as per attached...please share with me if there is something wrong with my circuit..tq

Obviously, there is very big mistake in your circuit compared to what Cytron give.

I bet there is no power at all on the stepper driver, right? But there is power on Arduino board.

The diagram from Cytron showing the power to adapter should be from adapter, not from USB and the stepper driver is taking power from Vin, which is from adapter.

You are supplying power from USB to arduino, there is no power on Vin of Arduino board, how can you power the stepper driver and stepper motor?

That 's why we normally ask for photo of actual hardware, everyone will say they connect exactly the same way, but not in reality

oo..ok...tq for ur comments....
