This mini-project is a simple demonstration of lighting up LED's in a braille pattern by controlling GPIO Pins of raspberry Pi using scratch GPIO version 2. Here is the link to the corresponding scratch project http://scratch.mit.edu/projects/10914464/.
1. Setup Scratch GPIO2 on a Raspberry PI.
2. Arrange LED's in a columnar manner on the breadboard such that each braille LED is connected with a GPIO pin on PI:
Braille LED 1 - GPIO Pin 11
Braille LED 2 - GPIO Pin 12
Braille LED 3 - GPIO Pin 13
Braille LED 4 - GPIO Pin 15
Braille LED 5 - GPIO Pin 16
Braille LED 6 - GPIO Pin 18
3. Open this Scratch Project with GPIO version.
4. Click the green flag on scratch project and see the magic!
