Programming help needed (arduino) - write a program that transmits a series of characters.
The sequence will consist of "AlphaNumber", where Alpha is meant to be a letter, cycling from A to Z, and Number is a digit that cycles through 0 to 9.
The sequence that comes out should look something like "A0B1C2D3....".
The objective is to send a letter-number pair every 500 milliseconds.
We will also want to be able to restart the sequence, so we will watch for a capital R to be received and once it comes in, restart the sequence at "A0". Set the baud rate to 9600 baud
Program structure
SetUp:
Set serial port baud rate.
Set up Timer
Loop:
if 500 milliseconds have passed
Send message
Update message
if serial data has come in
if serial data equal to 'R'
Reset message transmission.
