i am new to arduino coding, and i would like to interface a fingerprint scanner to sim 800l such that when a person enters a fingerprint, it sends a message to a specific contact from an array of contacts. i have already assembled the components together, and they are working. the hard part is to interface the scanner to the gsm module.
i'll appreciate if someone helps me
the hard part is to interface the scanner to the gsm module.
I don't see the need to do that. The Arduino reads from the fingerprint scanner, and writes to, or not, the gsm module. There is no need for the fingerprint scanner to talk directly to the gsm module.

am using arduino uno - i forgot to mention
it will use "if" statement, like, if input is finger id 6, sent message to the corresponding 6th contact in an array...
I thank God for I finally succeeded 
hey iam working on same project can you help me with the code but iam using r307 fingerprint sensor
