Networking and Communication
Connecting 2 Attinys

To keep it simple i used the 2x3 pinheader as the connection betwen the 2 boards
I tried to use the SPI protocol in order to make the communication but i was unable to solve some prblems i was having
In order to the Hello board to blink according to the ultrasonic sensor in board 1 i made the pin 5 as a input in hello board and as a output on the ultrasonic board
I needed to make the Tx and the Rx inverted on both boards so the Tx in board 1 is the Rx in the hello board

I tried to send a number to each board using serial, but I was having some problems because the number tranform in hexadecimal, so i had to change the code to adapt to this problem using the ASCII Table
In this communications assingment i used two "Hello World" boards and a PC to send the data to the boards
