I have a Picaxe- 18 High Power Project Board. Everything else works fine, but when I give it a command to make a pin high, all pins 0-3 go high. Any ideas?
Did you populate the board?
This might be very easy --I think this is a solder it yourself board. If so, you simply have some contacts on the back “bridged” with solder. You can get some desoldering braid and pull away some of the solder --or-- put the soldering iron right between the contacts that are bridged. Heat them both up until they melt then quickly remove the iron and blow (as hard as you friggin’ can) at the contacts. I have found you can break the “tention” the solder has when molten this way.
That makes sense…
Thanks, I’m going to check that right now.
Rosin?
I just checked and the only thing between the coonnections is the rosin from my solder. Is rosin conductive?
Nope.
I just looked at the pathways on it, and it looks like all the positive side of pins 0-3 are all connected. I tried reversing the plugin of my RGB LED, but then nothing happened. I’m really confused.
Picture
No problem, we can fix this. I need a clear picture of the top and bottom of the board. --I will tell you exactly what the issue is.
