In preperation for my final project, I decided to use a switch to create an LED ramp that changes from green to red as a person holds the button longer.
A sort of digital representation of of pressure gauge or a time signal of sorts
Trials and Tribulations
I used Eagle on Fusion 360 to design my circuit. I also decided to use the Attiny 1624 because it had the extra number of pins for my 5 LED output.
First thing I did was change out the bottom sacrificial layer of copper plate because it was really beaten up from previous assignments.
Here you can see why I needed to go back and thicken up the traces. Two things were happening.
1. the gap between traces were too thin
2. the mill wasnt calibrated properly when I set up the origin and z
After a successful milling, I added all the components to my board.
I had also put in some holes into the pcb during the design because I wanted to create a 3D printed encasing for the pcb once I finished. There is a fantastic function in Eagle where you can just build 3d file from PCB so it "perfectly" creates the negative space for the pcb to go in. However, in reality I had to push the walls a bit to make it easier for the pcb to go in
