in this week i try to use electronics printed circuit machine to use that to sketch the electronics circuit [electronics printed circuit machine by using software colled eagle it was also challenges as when we hit the ground and try to implement the design the issues that i face is because the machine that i have in fab lab Rwanda is monochrome printing one side printing on the top only.in my electronic design i have the input device is th device that have input device in that assignment the input that send information to the microcontroller colled switch button the using to receive the information by using serial monitor by using serial communication.

The step that are using to design the circuit in board.

i have the first it Design the circuit in schematics.

the second is to convert the schematics into the board.

convert design of circuit that are design in board into the png.

and to create the PCB outline.

I have converted my images from .png to .rml since its what the milling machine takes as input. I used fabmodules to convert input circuit images to rml. On Input format drop down I choosed image(.png), on output format I choosed Roland mill(.rml), and on process I choosed PCB traces(1/64). And continued selecting on machine I choosed SRM-20, other settings were made automatically then I clicked on Calculate button for converting it. .

that schematics show some configuration by using fab modules.

After calculation done on the image, the rml file is generated .

Now I have done the same thing on the edge cut file with some modification like on process I selected PCB outline(1/32) and on cut depth (mm): I entered 1.6 cause I want to cut through the board.

After calculating the path for the tool the RML file is generated.

this is the machine roland machine that are using to print the machine

that are tools using to design the circuit in board.

we use the software called v panel to set the machine.

Now that I have fixed the board on the bed, I am ready to setup the machine and start milling.

that are the machine when it finish to design my circuit

that are the final product of my circuit board to take from inside the machine

that are the picture i'm solder my circuit

that are final product of my circuit board.

protocol in programming.

my coding how it communicate in my coding communicate by using class first we create the class in c++ and after we can call it.

All file used in that week we can Downloard here

that are the code that are using in my input device

About input

we use serial communication to see result in serial Monitor

that is test
