OpenLog SD sparkfun. Code presenting on serial monitor but nothing writes to the SD card. #252

New to openLog SD. I am building a payload that has three generators each hooked up to a current and voltage sensor. Everything displays perfect on the serial monitor but when I take my 16 GB micro SD card out of the OpenLog it has nothing on it. The LEDs on the openlog work so I'm thinking something is wrong with my code. PLEASE HELP!

/* This program is Designed for High-Atmosphere Bolloon. This program reads data from three generators(motors) and Gyroscope store it temparaley before saving the data to a .txt

  • on a SD card.
  • 1st PROGRAMMER: CASIMIRO M DEFIGUEIREDO || 2nd PROGRAMMER: MEGAN ROBARDS
  • DATE: 03/28/2023
  • VERSION 1.0
  • NOTICE_______
    • AMPMETERS have a small variance from 0mA to 185mA (Assume all Read values below 200mA is 0)

*HARDWARE____

  • 3x Ampmeter
  • 3x Voltmeter
  • 1x Gryoscope
  • 1x Arduino Nano
  • 1x Arduino Nano Breakout board
  • 1x Arduino Uno Balloon sheild.

*CONNECTION__

    • Each Ampmeter requires 5v to Vcc and GND connection
    • Each Voltmeter requires GND connection
