Electronics Design

Introduction

This week we're told to redraw the echo hello-world board then add at least a button and LED then check the design rules "DRC" and finally fapricate it. So at first i selected Eagle as the software for circuit board design. To learn using Eagle i watched Jeremy Blum's Tutorial playlist

Redrawing The echo hello-world board

After learning how to use Eagle i started redrawing the board. At first i created new project with a new schamatic and board then imported The "Fab" Library then i started adding the components to the schamatic and connecting them.

After finishing the schamatic it is time for the pcb routing so i opened the board and started moving and placing the components after that i started routing the wires.

After redrawing the board i wanted to redraw it again differently so i did.

Modifing the board

Now it is the time to add the button and the led. I wanted to add 3 leds instead of 1 led so i added them and i added a button and a pull down resistor in the schamatic and started routing them in the board. And after finishing everything i checked the design rules and every thing was perfect.

Faprecating the board

After finishing every thing i made the pcb on the modela and started soldring the components.
