Arduino-Based Two-Way Pager




This Arduino-based pager by  Mike Schaus will allow you to send and receive real SMS text messages. This messaging device has its own SIM card and phone number.

Arduino-Based Two-Way Pager




In order to build this project you need the following parts:

And you will need to use this software to run the project: Hologram Data Router.

This project was made possible as part of Hologram’s Hacker-In-Residence program, The Hologram Global SIM Card allows you to connect you IoT device everywhere. Paired with a powerful device management platform and API. It provides a cellular data service that works with any device that accepts a SIM card. In addition it is totally inexpensive.

GSM shield, the Hologram things, and Arduino stacked on top of each other made a good combination to build such a project. For powering the project, Mike had used a 9V battery as an option, and still, powering from USB is possible.

Mike had designed this project so it could be used by children instead of a real cell phone, or it could be used as an “SOS” button for someone working alone outdoors or even exercising.

Check this video to know how this project works:

The amazing thing about Adafruit LCD shield that it only uses 2 pins of Arduino since it works over the I2C bus, which results with many places left for future features.

This is the schematics of the project: It is super easy, the wires mean putting the pieces on top of each other.
