Input Devices - April, 8th 2015

 
 






New Board

Here we are again surrounded by electronics. This time the assignment was to design the board with input devices.
I chose mine trying to be close to what I will need in my final project (Which I changed, by the way).
As an input device I chose synchronous detection, and used Neil's board as a reference.

Starting The Adventure

To perform the measurements I used Python. On Mac it is already installed, but I have had a lot of difficulties to make it work effectively.
First I programmed the board at Terminal. Everything was fine and the LED was lit up, but using Sudo previously...

Avrdude Done. Thank You!



Becoming a Nightmare

In the Terminal, after saving on my desktop the three required files in a folder that I created (hello.reflect.45.c , hello.reflect.45.make , hello.reflect.45.py) I had to experience many obstacles trying to find out what was going on, and why python didn't want to work for me!!!

Python on Mac

After to rechecking a thousand and one possibilities, finally with a lot of help and patience of my instructor Ferdi, we could figure it out how to make it works:

                  
http://brew.sh/
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install python
pip3 install pyserial - You should install this (in my case)

from Tkinter import *
from tkinter import * - You should change this at the file

print (command line: hello.light.45.py serial_port)
#print (command line: hello.light.45.py serial_port)



The Right Code
