You should start by making a chart of WHAT your program should do, like this, and by this you can start making your own flowchart based on that:
For example the program base could be like this:
For example the program base could be like this:
Code: Select all
**START**
**Startup**
- Program loads password from EEPROM to variable (so safe system... okay, maybe not.)
- Program initializes the GSM modem and checks if there is connection...
**Loop**
Program checks if new messages available
if message available, check if it contains "r c pass" where the r is relay, c is control and pass is password.
if pass was not same as eeprom pass, then set password_right to 0 and send wrong password message back and return to start of loop
else if password right then: * put stuff here to select relay and turn on or off respectively * then reset the password ok part
return to start of loop
**END**
Ill just keep the good work up!

Success always occurs in private and failure in full view.
