 **Accomplishments:**
 I have had some experience working with Arduino and 412 in the fab academy prep session we have had and so 
 I revisited the 412 for bare metal programming but focused mainly on the RP2040 and the Arduino.

 # 7. Electronics design
 
-This week I worked on defining my final project idea and started to getting used to the documentation process.
+In this week group work our goal was to use the test equipment in your lab to observe the operation
+of a micro controller circuit board.
 
-## Research
+Our group used an oscilloscope, spectrum analyzer and multi meter to measure elements of the 
+RP2040 based board we build Fax Xiao made buy ADRIÁN TORRES [here](https://fabacademy.org/2020/labs/leon/students/adrian-torres/fabxiao.html) as well the RP2040 based Morse Code generator I created in embedded programing week

+Design a development board to interact and communicate with an embedded microcontroller
 
-## Code Example
+Extra credit: try another design workflow
 
-Use the three backticks to separate code.
+Extra credit: make a case for it
 
-```
-// the setup function runs once when you press reset or power the board
-void setup() {
-  // initialize digital pin LED_BUILTIN as an output.
-  pinMode(LED_BUILTIN, OUTPUT);
-}
+Extra credit: simulate its operation
 
-// the loop function runs over and over again forever
-void loop() {
-  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
-  delay(1000);                       // wait for a second
-  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
-  delay(1000);                       // wait for a second

+## Learning Eagle and board #1
 
-### From Youtube
+I have never design a board and so I was very excited to get going on this one. I decided to try 
+out Eagle as that is the focus on most of my classmates this week. 
 
-<iframe width="560" height="315" src="https://www.youtube.com/embed/jjNgJFemlC4" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
+I went through the 5 part tutorial as a starting point [here](https://youtu.be/_jgUZeBiusw)
 
-## 3D Models
+I then decided to try an replicate the Vegetable Washing Machine control board I programed in embedded programming week you can see [Here](https://fabacademy.org/2023/labs/charlotte/students/dan-stone/assignments/week05/#arduino-and-the-vegetable-washing-machine-basic-set-up)

+I started off by set up my Eagle work space and enabling some libraries, in particular finding the one for SEEED RP2040
+
+![Library](../images/imagw6/D1Seed.png)
+
+I then pulled the parts into place 
+
+![Placing](../images/imagw6/D2.png)
+
+Next was adding all the rest of the parts and made the base set of connections 
+
+![Connections](../images/imagw6/d3.png)
+
+I wanted to get the board all clean and so added the values of each resistor
+
+![Values](../images/imagw6/D4.png)
+
+I used the inspector window on the side to quickly access info to speed things up
+
+![Clean up](../images/imagw6/D5.png)
+
+I then grouped and labeled parts - please note that I used LEDs to stand in for a motor and pump and will 
+replace with connectors in the next rev
+
+![Grouping](../images/imagw6/D6.png)
+
+and finally put a frame around it and we are good to put to the parts placement 
+
+![Parts](../images/imagw6/Place1.png)
+
+I then started to move the parts into place 
+
+![All Parts](../images/imagw6/Place1.png)
+
+
+I moved the parts into the general areas I had in mind for them
+
+![Placement](../images/imagw6/Place2.png)
+
+
+I started putting down the routes but ran into the puzzle in the top right with a landlocked connection. 
+
+![Landlock](../images/imagw6/Place3.png)
+
+I used the resistor as a bridge 
+
+![Bridge](../images/imagw6/Place4.png)
+
+I however figured out at this point that I was using the wrong resistors and needed the surface mound components 
+rather then the drill through and so I had to go back and start replacing the resistor in my schematic 
+
+![New resistors check](../images/imagw6/Place5.png)
+
+I  had to redo the placement and routing with the new components 
+
+![New resistors](../images/imagw6/Place55.png)
+
+That seem to work well and so I did the same for all of them
+
+![All new parts](../images/imagw6/Place6.png)
+
+I still had the land locked resistor and now the SMD component I choose was too small to be a bridge 
+and so I used one of the larger resistors as a bridge   
+
+![Done](../images/imagw6/Place7.png)
+
+And here is the overview of the schematic 
+
+![Schematic](../images/imagw6/Place8.png)

+## Making a box and board #2
+
+What I have found to be most confusing so far are libraries and which ones to use but I think 
+that I bit more practice and this will become clearer 
+
+I decided to start over and this time use the ESP32 and focus what could be the board for my final 
+project. Since I plan to break out the electronics to main board and break outs for LEDs, buttons etc. 
+so the main board should have connectors set up. 
+
+
+I started off by desiging the box for the board 
+
+![Box](../images/imagw6/Box1.jpg)
+
+
+![Box shell](../images/imagw6/Box2.jpg)
+
+
+![Box design](../images/imagw6/Box3.jpg)
+
+I then created the board profile 
+
+![Schematic connection](../images/imagw6/Box4.jpg)
+
+
+I connected it to the schematic
+
+
+![Schematic](../images/imagw6/Box6.jpg)
+
+I got the connectors set up for the motor and water pump, operatings button including the pull down resistors 
+LED indicators and power
+
+![Button](../images/imagw6/Box7.jpg)
+
+I group and labeled everything 
+
+![Labels](../images/imagw6/Box8.jpg)
+ 
+ and started to place the components 
+
+![Placement](../images/imagw6/Box9.jpg)
+
+
+![Placement](../images/imagw6/Box92.jpg)
+
+
+An routing .... however I hit road blocks with too many crossing connections 
+
+![Routing](../images/imagw6/Box93.jpg)
+
+I took a 2 part approach both rewiring some of the connection by switching IO pins which did not matter to 
+my code and moving some of the connection around on the board
+
+![Rework](../images/imagw6/Box94.jpg)
+
+That allowed me to get everthing routed and pushed to 3D
+
+![Done](../images/imagw6/Box95.jpg)
+
+
+![3D](../images/imagw6/Box96.jpg)
+
+Now I wanted to see it in the box I created.  So I made a new file so I can bring in the box and the board 
+
+![Combined file set up](../images/imagw6/Box10.jpg)
+
+I inserted the box
+
+![Combined file set up](../images/imagw6/Box11.jpg)
+
+and the board 
+![Combined file set up](../images/imagw6/Box12.jpg)
