I’m not experienced enough to make up my own sheet completely on my own. How do i then change my sketch to implement the last two additional pins of the chip?

Or so i thought. I’ve edited several other questions with this issue. Sign up using Facebook. Email Required, but never shown.

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 Just not sure what i do with my driver having one more pin than the one in the toturial.

As a driver for the motor i bought a ULN driver datashedt from Ebay. It might’ve been a careless mistake derived from laziness since the chips have the ratasheet type of circuitries.

These chips are commonly use for this application. As I am not a native speak, those rules are easily forgotten.

It looks like the same application and same specs, set of darlington arrays. Will try to improve now that I’m aware of it: 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. A lot of people seem to think Datashheet attacking them, but I’m just interested in the quality of the site. And how do i alter the sketch to work with an extra pin on the chip?

Post as a guest Name. This example looks fine. Please capitalize “I” when referring to yourself. Only in this circuit, you’d datasehet in8out8 pins setup the same as in7 and out7.

I have an unipolar stepper motor that im driving with an Arduino. Thanks for your efforts! I’m unexperienced in how manufacturers set the numbers on the chips. You can find many tutorials online.
