Or so i thought. As a driver for the motor i bought a ULN driver chip from Ebay. A lot of people seem to think I’m attacking them, but I’m just interested in the yln2804 of the site.

As I am not a native speak, those rules are easily forgotten. I’m not experienced enough to make up my own sheet completely on my own.
It looks like the same application and daatsheet specs, set of darlington arrays. Email Required, but never shown. So, can it work to power my stepper?

Here’s the pdf for the ULN chip It looks like the same application and same specs, set of darlington arrays. I have an unipolar stepper motor that im driving with an Arduino.

Just not sure uln2840 i do with my driver having one more pin than the one in the toturial. Here’s the pdf for the ULN chip.
I might be missing something, but the chip i received has 9 pins on each side, not 8 as my sketch illustrates, and the number on it is ULN, not ULN JYelton Thanks for the feedback! Sign up using Facebook. This example looks fine. Thanks for the response. Will try to improve now that I’m aware of it: How do i then change my sketch to implement the last two additional pins of the chip?

I’ve edited several other questions with this issue. You can find many tutorials online. I’m unexperienced in how manufacturers set the numbers on the chips. Only in this circuit, you’d have in8out8 pins setup the same as in7 and out7. Sign up or log in Sign up using Google.
