@ codlink - thanks, that is a pitty they don't allow internal cutouts. I guess they are fine with irregular shapes though so my design should be OK? I best start renaming the parts then
I do remember some people saying they will cut along the dimension lines, but I have have also heard of irregular boards coming back un-cut. I would email them to make sure. I forget their direct email, but you use the contact us page.
I've been getting this too. I am having to keep refreshing to see my posts. It's funny it says to report to admin, but there is no link or button or...
Also the "Mark Read" isn't working very efficiently. I have to click it 3 or 4 times to get it to work right. First time I click all the posts are set to new, click again and some of them are read, then it takes 1 or 2 more clicks to get them as read.
I have also seen if there are images in a post, I click on one and it says I don't have permission to view it. I refresh and then I can view it.
We need a dedicated bugs thread. I have seen more than these that are listed. They just don't happen as often to annoy me. I know you guys behind the scenes are working on it. Take your time and do it right. Thanks for the hard work.
PS - The image attached is what I get when I post or even open a topic. I have to keep refreshing for it to come up. The second image is when I try to view the first image.
NOTE: The board on that site is not the same as yours. But if you look closely, they both have the same pinouts. BTW, I found this on the first page Google searching "arduino l298."
I agree that a pneumatic system would be the quietest. Google would be your best bet.
I have a pneumatic system moving the arms of a humanoid robot. The air cylinders come in many different sizes. Ebay has tons of them. Arduino can control the system through relays.
That vague answer was a response to your vague question. First we need to know what isn't working. What is the serial monitor printing? And, possibly how you have it wired.
