Braille Printer
Introduction
This project implements a complete version of a braille printer. You just insert your sd card with the desired files, select the one you want, insert the paper, and the print is done!.
I picked this project based on one question:
What can I build using scrap i have in my house for some reason?
After searching inside some boxes I found the main part of an old printer. (the head that moves on the x axis in order to put the ink down)
So this project was (almost) built without paying for anything.
General Description
For this project to work I had to use two arduino uno boards (for gpio reasons).
Here is a list of every component:
- Arduino uno (the brain) - let's call it 1
- Arduino uno (the consumer) - let's call it 2
- ILI9341 2.8' LCD with touchscreen
- SD-card reader (from the lcd shield)
- 2 stepper motors (bipolar, 12V, don't know the name)
- 2 A4988 drivers
- 3 push solenoids (built myself because they are small)

Hardware Design
- listă de piese
- scheme electrice (se pot lua şi de pe Internet şi din datasheet-uri, e.g. http://www.captain.at/electronic-atmega16-mmc-schematic.png)
- diagrame de semnal
- rezultatele simulării
Software Design
- mediu de dezvoltare (if any) (e.g. AVR Studio, CodeVisionAVR)
- librării şi surse 3rd-party (e.g. Procyon AVRlib)
- algoritmi şi structuri pe care plănuiţi să le implementaţi
- (etapa 3) surse şi funcţii implementate
Rezultate Obţinute
