But is this project really a ‘Robot – work in progress’ ? It probably should be posted under ‘Something Else’ .
And it might be a bit early to ask for cool patterns before you have the cube working. As far as I can tell your only testing the LEDs manually on the video.
PS. I would also recommend that you start using a breadboard on your projects and get the system to work there before you solder anything at all. And never solder any chip directly on the board if you can avoid it.
If your LED lights up from the soldering iron I would consider buying a new one. To me it sound like some current is leaking out to the metal of your soldering iron and the wall plug didn’t look like a grounded plug. The LED might act as a part of a rectifier bridge and what your seeing is actually PWM at the frequency of your AC supply.
I’m really not sure. You might put a post up on the forum as that is the proper place for this question. If the voltage/current is not enough to give you a shock, you might end up frying some component while soldering them.
IRIS Systems is a company that sells electronic flame monitoring systems. The logo and typeface you are using in your avatar is almost identical. This was not intentional?
1. I understand perfectly, 1. I understand perfectly, but I had a 40x1 on hand and didn’t want to complicate an already fine system.
2. Sounds like a good idea, but again, I already have a working system
Actually, I’m still using Actually, I’m still using some NPN transistors. To make the columns negative you set it to high.
Again, another excellent idea, but I’m just going to keep it simple because I want to move on. Also, the code looks like it takes up more program space. Personally I would like a larger variety of patterns then LEDs of different brightnesses.
