                      1.  Karthik is programming an Arduino to control an LED based on sensor data. Which Tinkercad
                         programming mode is best for Karthik, a beginner, to start creating the program without
                         writing code?

                      2.  Sanya is programming her Arduino to turn on an LED when the soil moisture is below a certain
                         level. Which type of block should Sanya use to perform the comparison of soil moisture?
