Assignment XIX Project development

Project Development

What tasks have been completed, and what tasks remain? 
Well, I tried to complete all tasks. 
So, the last one was about the interfaces and it took me much time to learn the processing. 
What has worked? 
The boards of LEDS added to Arduino Medusa has worked. I could switch them on. 
The conductive thread is just like the normal cable.  
What hasn't?
During the project development some boards I milled did not function. 
The Modela is good for milling small boards. 
Some vias of my arduino elevated and some pins of microcontroller were removed. 
The second one was milled  more or less satisfactory but did not function because I made a mistake. 
I used the crystal 20OM instead of 16OM. 
So the third one I milled with Gravograph and the result was excellent. 
What questions need to be resolved?
How to design an electronic board?
How to fabricate it?
How to program it? 
What will happen? And when?
 So, when you connect the arduino to the battery, it is ready to work. 
Then switch on the LEDS with only one button!

Push once and the left LED switches on. Push one more time and it will turn down.
Push twice and the left LED switches on. Push one more time and it turns down.

In two mounths I`ll organize the maker fair for young people to 
show how to use the electronics for everyday life.  
What have you learned?
I`ve learned the electronics, how to use Roland Modela, Laser machine and  the CNC Shopbot. 
Documentation during development is the most difficult part because it is very time consuming.
