Train Scholarship (Genaro Rivera)

  I finished soldering and made the code. I finished soldering. The soldering dragged due to my inexperience soldering skills and the tiny pads. To accelerate, Rik, experienced with soldering, helped so I waste little time. I made the code. The code involved downloading the Arduino, sensirionI2CScd4x (found in spec sheet), wire (AKA I2C), Softwire (for compatibility of digital outputs on our analogue flight data recorder), and AsyncDelay libraries. Firstly, I declared the analogue pins, but note that we intended initial testing on a digital Arduino to reduce confusion regarding sensor malfunction or set up on our analogue board. Additionally, we initialized the variables and libraries using a void set up design to loop through once. Within, Serial.begin(115200) initialized serial communication with a baud rate of 115200. Wire.begin() called the I2C library: within the parenthesis is the master, so we included nothing within to make the Arduino the master. Scd4x.begin(Wire) initiali...
