Hey all,
I have a little project from school that I need some help understanding/guidance.
What I am given: Arduino GSM SIM900 Shield.
What the project is: I need to code so that every five minutes i give it a command. after the command is given i want it to go straight to sleep for the rest of the five minutes. i need this to happen over and over while producing the least amount of energy possible and requiring the minimal voltage.
Any help would be greatly appreciated.
Mel
