Ok so I am new to the program but I have been getting on with it fine throughout my first projects until now. Just for reference I have the newest version of KiCad (5.01) for Mac with all the bits and I am using High Sierra.
So for this project I had made a complicated schematic and had it all working and then went on to design the PCB. I then refined the design and decided I could swap a couple components to make it cheeper and more efficient. Here is what I did next and my issues:
- I removed the unnecessary components from my schematic. That included a transistor and a 3 pin voltage regulator.
- I then replaced them with a 5 pin voltage regulator which I had to make a new schematic for. As far as I am aware I did everything correct in the making process and the label it was given was U?
- The photo shows that part of my schematic with the newly created component. The Vout leads to a piezo buzzer and the (BUZZ) tittle leads to a pin on my arduino. <<First issue I am getting an error stating pin 3 is connected to BUZZ and to GND. Its not, I dont know why its saying this?
- Next I went to annotate the schematic symbols and my new component became U02 temporarily.
- Next to assign it to a foot print. << next issue my component did not show up in the list for me to assign a footprint to it.
- Back into my schematic I notice my component is now labeled #U02 << 3rd issue, what is the # symbol all about and why did it show up?
Additional note: I tried adding another random component and that one behaved normally so I believe there is something wrong with my created schematic. What I dont know.
