Voltage Spikes on Digital Pin

Many thanks for your feedback. In a way I am relieved by your comment that something is wrong with my project. Being a novice in this area I was not certain that something was indeed wrong based on those traces. I interpret from the remainder of your post that there could be many explanations for what is observed on the traces, which in itself is useful information for me if I am interpreting you correctly.

I certainly wasn’t trying to hide information from anyone. I thought that it might be expedient to filter out if there was a problem at all, or if the issue stuck out like the proverbials, before I swamp the thread with what could have been unnecessary detail. Now that you have clarified that there is definitely a problem to be addressed here I will compile the additional information you have suggested, and post this.
