I am interested in making a pcb board project. I think this would be a good tutorial for others as well. As interesting as Jeremy Blums Blinky Board Tutorial is, I want my first project to be a shield that I can use with my arudino projects.
I want to do this, rather than the blinky board, that way I can play with it after it comes in. The blinky board is interesting, but after you get it and power it up and see it blinks, there isn't a lot that you can do with it.
So I was thinking an Led shield that basically just has an led with resistors already built in for each pin of the arduino would be neat. This way I will be able to use it for other applications, and won't have to use a breadboard and find an led and the needed resistors each time I want to do something with an led.
Another possibility instead of the led shield, I was thinking about making a HM-10 shield. I have an HC-06 module, but you really have to use a bread board to connect it to an arduino. With a shield, it would be an application that I could use on other projects, of course if I just wanted a bluetooth shield there are probably cheaper options, but I am more interested in learning how to make a PCB board and really like to learn by doing things that have useful applications that I find interesting and useful.
I have already download KiCad, and believe it will be more useful as I saw a few reviews for Eagle that arduino size boards on Eagle cost an arm and leg.
So my questions are:
- Which of the two projects mentioned would be ideal for a beginner?
- Is there a library or a schematic already made for a blank arduino shield that is the size that it needs to be, has the pins already there that connect to the arduino?
- If I do the led shield, would I be able to use it if I use it with a sd card shield or Ethernet shield later on or will the led mess with the functionality of the sd card or Ethernet shield because it will power the led when the pins are active?
