Electronics design
This week assignment is to redraw hello-world board and add a button switch beside LED then we have to cut the board as per the the schematic diagram and solder the whole circuit parts.
Drawing hello-world Board
Initially i experimented with Eagle, Circuit maker and finally KiCad. Then i decided to go with Eagle since i findit is more intuitive Then i downloaded the specified component library fab.lib from the FabAcademy website added it to the library of the eagle.next step was to obtain the hello-world board from website
From the details obtained from sample image i began to draw the schematics using eagle software. Initially i placed the components from libarary to schematic area.
The components in the initial hello-world board are
- ATtiny44 x 1
- Resistor 499ohm x 1
- XTAL 20HZ x 1
- Resistor 10K x 2
- Capacitor 10uf x 1
- Push button x 1
- ISP header x 1
- FTDI header x1
- LED
final view schematic after the redrawing

After Generating the schematic we can use generate option in eagle to obatin the board design. After Rearranging we will obtain the output as below
After auto-routing the board we will obatin below output
