Today i received the GSM shield for Arduino from Open Electronics. I rushed to get a pre-paid SIM card to start playing with the new toy.
I just realised that i don’t have an arduino board yet in my personal toolbox, but i can borrow one from the hackerspace to start experimenting.
I have two projects in mind:
- mailbox watcher: Since the mailbox is far from my apartment and not within my regular walking path, (and i am a lazy person ;-)), i want the board to send me an SMS when a letter is landing in the mailbox. This is also a nice opportunity to experiment aggressive power saving and see how long can a set of fresh batteries last.
- Hackerspace door opener: I am also building a motorized lock for the local hackerspace. I don’t know yet what kind of remote control we can use, but it has to be democratic enough. This is not the most original project: the Ghent hackerspace already did it.
GSM shield assembled
The shield come as a kit, some soldering is required, but nothing too serious (only through hole components, 2,54 mm pin spacing). In my case, only the switch SW1 was tricky to install.
That’s all for the moment, time to write code.
