Week 2 Component testing and modeling

The second week was spent on initial testing of the modules purchased in the first week, searching for information and writing test codes to check that the modules were working properly. The following mods were tested: nRF24, LM393, BMP388, DS3231, OLED, DHT22, SGP40, SD Card, Rain Sensor, EC12.
