evantimms / arduinoChatProgram

This is a simple chat program that allows two Arduinos to communicate via their serial ports. This program was developed in two stages, the first was a simple unencrypted chat that allowed simple communication that displayed on two computers monitors. The second version implemented XOR encryption using the diffie-heilman procedure as well as adding better functionality.

Notes: Some code(along with comments) provided in class was reused indirectly throughout the assignment
accessories:

*2 Arduino Mega Boards (A and B)
*3 wires
*1 Resistor

Wiring Instructions

Pin TX3 (Arduino A) <--> Pin RX3 (Arduino B)
Pin TX3 (Arduino B) <--> Pin RX3 (Arduino A)
GND (Arduino A) <--> GND (Arduino B)
5V (Arduino A) <--> Resistor <--> Pin 13 (Arduino A)
GND (Arduino B) <--> Pin 13 (Arduino B)

To run:

*Wire together the Arduinos
*Upload the code into each Arduino
*Open separate Serial monitors for each Arduino

Special Notes:
*A hard reset is required once both serial monitors are open or else timeouts
will occur.
