 Most of the projects you'll do with BLOX will involve an event in the form of a sensor or other input kicking off something that needs to happen

+===== 6.3.1 Analog Sensors =====
+Analog sensors measure values that can vary continuously within a range.
+For most simple sensors, the value from an analog sensor is typically represented as a changing voltage, which your BLOX converts to a digital number (0-4095 as ADC is equivalent to 0-3.3v at the analog input terminal)
+Some more advanced sensors uses I2C or SPI to communicate and provides a more direct value like a temperature or distance in actual units.
+You usually respond to analog sensor readings by setting thresholds. For instance, if the temperature exceeds 30°C, you might trigger a fan to turn on, and if it drops below 30°C, the fan stays off.
+This approach allows for more nuanced control based on the varying data the sensor provides.

+===== 6.3.2 Digital Sensors =====
+Digital sensors work like a simple switch, offering just two possible states: on or off, triggered or idle.
+For example, a motion sensor might detect movement (on) or no movement (off).
+Since digital sensors only have these two states, your program simply need checks whether the sensor is triggered or not and reacts accordingly.
+This type of sensor is often used for straightforward tasks like detecting the presence of an object or whether a button has been pressed.
