The purpose of this project was to send a text notification when someone pressed the door bell. Maybe you are outside or in the back of the house, out of hearing range of the door bell's ding-dong. Maybe you want to know how many people stop by while you are away from home. Maybe you just want your door bell to text you for no reason other than you just freakin' want it to! Whatever the reason, here is how I built mine.
This project uses high temperature soldering irons, power tools, and deals with A/C voltage. I am not responsible if you burn yourself, mess yourself up with power tools, or if you do the electric shock dance (or die) from touching live A/C current. Please be careful and if you do not feel comfortable with one of the steps, find someone with experience who can help you, or maybe this isn't the right time in your electronics hobby career to be trying out such a project. Happy making!
I have a few ideas for expanding this project in the future. The first idea is to be able to set up "quiet hours" for when you want the doorbell to text you, but not actually ring the doorbell. This would be great if you have a sleeping baby.
Another idea is to change out the old fashioned "Ding-Dong" doorbell for an mp3 shield and some speakers so you could play custom songs for your doorbell.
The options are limitless, if you have any great ideas to add to this project, I want to hear about them. Send them to me!
