Ok, new update, don't know why that was but that first condition is gone. Basically when everything is on, the red LED is off and I'm just going to resolder my joints again.
2  Using Arduino / LEDs and Multiplexing / LED Strip One color not working on: October 09, 2012, 09:13:21 pm
I'm working on this project amblone  http://amblone.com/guide

And basically I'm at the point where I'm done, only that for one strip, the red color is not working. I have troubleshooted and troubleshooted and cannot find the problem. I have a total of 3 led strips and the other 2 work perfectly. Here are the conditions

1. When I touched ONLY the lead of the power supply to the positive commons of all the LEDs, the green LED lights faintly on the defective strip while the other two stay unlit. The negative from the power is NOT connected.

The wiring and soldering should not be an issue, is it a possible transistor issue? Because maybe one of the legs got heated for too long? Any advice regarding this would be helpful.

Also the one PIR sensor is particular is to power all the LEDs at a dimmed level, while each LED has their individual PIR to power them at full brightness.
I fail to see how a PIR sensor can power any LEDs. No more than a light switch powers a light on the ceiling. If the switches powered the lights, what would we need the power company for?

I read the OP as really meaning "control" when they used the word "power", an understandable novice mistake.  Yet, it is something that should be corrected because not using the proper terminology will only cause confusion.

Thanks for the correction I'll remember that.

My first question is can PIR motion sensors be placed in any other pins besides  PWMs?
Where did you get the idea that a PIR sensor was read on a PWM pin? PWM is an output capability. It has absolutely nothing to do with how an input pin behaves.

I read a schematic on how to connect a PIR sensor to a board, and realized that the pin it was connected to was not specifically marked PWM like the rest of them. So I can assume I can use any digital pin, including those that have PWMs.

Hi! I am working a project consisting of many LEDs strips and PIRs. My first question is can PIR motion sensors be placed in any other pins besides  PWMs? If not, what is the biggest board that has the most PWMs? I am working with about 8 White color LED Strips and each one is independent to other strip. Also the one PIR sensor is particular is to power all the LEDs at a dimmed level, while each LED has their individual PIR to power them at full brightness. Thanks for answering my rookie questions.

Thanks a bunch! I removed the header which took just a little wiggling and finally got it up. One of the actual pins in the header snapped but i think it can still conduct! But lesson learned, do not bend the copper.

Hey! I accidentally snapped a copper wire in one of the pwm pins. I tried using a needle to get it out but i won't budge. So if I unsolder the bottom of the pin and poke out the copper, will that be safe and not damage the pwm circuit? If not, is there any better alternate solutions before I go ahead and potentially ruin my board? Any help would be great thanks.
