|  | Electronic Design This week we needed to add a button and an LED to the hello.echo board. Using Eagle I added the button and switch to the schematic.   I milled the board using Dr. Engrave software. The first board I milled combined lines from the 6 pin to the resistor at the top. The second board was milled bigger than most of the components.   |
