As I mentioned in my previous blog post, I designed the proximity-sensing LED circuit to eventually move it on to a printed circuit board, or PCB. This was my first experience with PCB layout, and thankfully it was successful! The board I designed is in the picture below. We ordered 6 “prints” and soldered them in our MakerSpace. I also included extra vias (electrical connections between the layers of the board) so that we could connect multiple boards together.
If you’re interested in learning PCB layout, I posted an Instructable on my design process. You can find it here. I will also be teaching a PCB layout course in our MakerSpace next Thursday. I used CadSoft’s EAGLE software to do the layout, and CadSoft offers a freeware version of EAGLE so anyone can do this! A link to the Instructable will be posted here very soon.
