Wondering if I did't forget to add anything


This is my first electronic project with Arduino and Adafruit components so before I power it up I would like to get confirmation that I haven't forgotten anything.

The goal is to create a device to detect a car in a parking space thanks to a magnetometer. This device is supposed to be powered with batteries (2 of them) that are recharged with solar panels.

These are the components I am using: - Aduino MKR GSM 1400 - Adafruit Triple Axis Accelerometer + Magnetometer (Compass) board - LSM303 - Adafruit USB / DC / Solar Lithium Ion/Polymer charger (x2) - Adafruit Lithium Ion battery - 3.7V 2500mAh (x2) - Adafruit Medium 6V 2W solar Panel (x2) - Adafruit Power Boost 1000 charger - rechargeable 5V Lipo USB Boost @ 1A - 1000C

And this is how I wired it:


My question is: Is connecting all this components like this enough or are there any resistor, capacitor or any other component that should be added in the circuit?

Thank you all for your help.

Hi, Welcome to the forum.

Please read the first post in any forum entitled how to use this forum. http://forum.arduino.cc/index.php/topic,148850.0.html

What is your project supposed to do?

Why do you need two sets of PV/Battery assemblies to power your project?

What is the application?

Where is the GSM?

Thanks.. Tom.. :)

Hi, thanks for the answer.

The project is supposed to remotely monitor a parking space.

The two sets of batteries because the Arduino MKR GSM 1400 needs one battery for the GSM communications (if I am not mistaken :) ) and the second one is to power the Arduino itself.

As I need this system to be fully autonomous, I added a solar panel and a solar charger for each one of the batteries and because the Arduino needs to be powered up on 5V, I added a power boost too. I might be completely wrong but I thought it made sense at the time :)

The application will be to monitor the parking space as I said and then update a database with the status of the sensor.

The GSM is included into the Arduino MKR GSM 1400 board.

I hope that clarifies but if not feel free to ask for more details.
