good day everyone!

i starting on project uses arduino , gsm module (a6 ai thinker).
attached below desired outcome of whole system.

the problem new knowledge of using processing software to  interact gui arduino.
 
any suggestions on software use make easier or less complicated?

i don't quite understand on how every phone numbers input stored , sent , read arduino.  :smiley-confuse:

one more thing. can show me sample code of loop sending sms 1 @ time each phone numbers being registered?

thank in advance!
