Unlike the previous project, now I have a lot of parts that (hopefully) in the end will become a whole project.
So I decided to work on each part separately and then combine all of them together.
First part - "printing" a circuit
Because I want an organized circuit as possible and because I really want to use the milling machine I decided to create my own board. So I first started with planing my circuit. I want 4 different kind of buildings - 12 buildings in total. So for that I needed the analog inputs but the Arduino only have 8 analog inputs. I decided to use a MOSFET (which is like a switch) and connect it to the digital input.
Then with an help of a friend I created a circuit in a program called eagle.
in the middle of the milling process the tool broke so I will need to do it again. The lesson is to plan the circuit much wider and then to use a bigger tool
Part two- fabrication of the buildings
After I had the board sizes I knew each building's width. So I found a big piece of wood with the width I needed then I cut it to 12 blocks and then cut them to different heights. After I had my 12 blocks I sanded them a bit that they will be straight
So I got 12 different heights blocks
I wanted to create windows that will look like buildings. I'm not sure if I want to color them or use vinyl sticker on them but anyway I created the vinyl so I can use as a sticker or as a stencil for coloring
The only thing that is left in the building fabrication is to make a small crack for the resistor. So with the help of a hand saw:
I did small crack that the resistor can go in:
I'm planning to glue some kind of conductor material on the bottom of the building.
part 3: P5 programming
I continued to program from last week and add the options that if there is a building the sun and air lines will reduced
A situation were there isn't any building:
A situation were there are some building:
That was my original plan but now I think of adding a few thing like sound and volume
will change with every building added. And maybe instead of the grass disappearing I can draw buildings like in my vinyl cut file:
But is still depend on whether I'll finish everything on time.
Things left to do:
- Painting the buildings and gluing a conductor martial to the bottom
- Connecting the circuit
- Fabrication of the baes
So this week I didn't have most of the parts, so I order them. I tried to find a few in the ITP shop and luckily I found the Digital Potentiometer.
So until the other parts will arrive.. I started this lab
SPI Communication With A Digital Potentiometer
I started by connecting the board
then I attached the speaker to the Arduino and with resistor to the Digital Potentiometer.
After writing the code it didn't worked:(
I tried to debug it and notices that one wire was connected wrong so I change it. but unfortunately it still didn't work. I suspect that that there is a problem with the Potentiometer but I'll have to replace it to find out.
