Make an Old-school two-way pager with Arduino

I made a 2-way pager with an Arduino, GSM shield, and LCD shield. I’ve found this idea to be more useful than at first glance—I designed it so it could be used by children in lieu of a real cell phone, or it could be used as an “SOS” button for someone working alone outdoors or even exercising (if it was a bit smaller). And for the last few weeks, this device has been always on in my living room where my wife and I leave silly messages for each other.

Summary: This project sends and receives text (SMS) messages via an arduino with cellular modem built into a small enclosure with an LCD display and simple control buttons. Full details of the design and build are on Hackster.io.

Could also be called "Most expensive pager made in 2016 ever."

Update: People seem to like this project! It has over 10,000 views, and was even featured on Hackster’s Handpicked Projects of the Week.

How to make a cellular-connected garden monitor

Check out this project I made to monitor the soil moisture level of my remote garden plot. Since the garden has no power or internet available, it uses a cellular data connection to send info back to a cloud service, and then that data gets passed to another cloud service for plotting. A great learning experience!

I posted all the details on Hackster.io, a community for hardware makers with lots of interesting projects:
