It's now time to assemble the hardware of this project.

First, connect the power supply to the breadboard: connect the 5V pin from the Arduino board to the red power line on the breadboard, and the GND pin to the blue power line.

Then, place the FONA shield on the breadboard. Connect the VIO pin to the red power line, and the GND and Key pins to the blue power line.

After that, connect the RST pin to Arduino pin 4, TX to Arduino pin 3, and RX to Arduino pin 2. Also connect the 3.7V LiPo battery, the GPS antenna, and the GSM antenna to the FONA shield.

This is a close-up picture of the shield after the project was assembled:

And this is an overview of the whole project assembled:
