Solar Panel 6V
changed the cord to plug into a converter to charge the Battery
Battery can output to USB to charge a cell phone however this will be used to power the Arduino Micro the the preamp for the Adafruit mic with preamp included on the chip. I built this as a phone charger mainly because I hadn’t decided the sensor I would be using and was contemplating using an old iPhone as the data logging device. I also felt that USB output would allow for me to easily swap out the sensor without being too worried about redoing the solar panel setup.
I used the Adafruit solar kit for their ‘solar bag battery charger’ project but assembled it for this sensor data logging project. Ran into mainly issues with the connector but i cut up an arduino power cable and soldered it to the output of the solar panel and its fine now.
