Today we are going to finish the pcb gerber files so that our print is made and we can finally start with soldering. Our program in arduino is still not 100% this is probably within the i²c part of the code. To test our program we are using a test setup with 1 i²c, 2 pullup resistors of 4K7 and a led. The schematics of the test setup you can see in a former blog.
