1. A method of controlling a control body coupleable with a cartridge that is equipped with a heating element and contains an aerosol precursor composition, the control body being coupleable with the cartridge to form an aerosol delivery device in which the heating element is configured to activate and vaporize components of the aerosol precursor composition, the control body including a first positive conductor connectable with a power supply, a second positive conductor connectable with the heating element, and a series pull-up resistor and switch connected to and between the first positive conductor and second positive conductor, the switch being connected to and between the pull-up resistor and second positive conductor, the method comprising:
operating the switch in a closed state in a standby mode in which the pull-up resistor is configured to cause a logical high level of voltage at the second positive conductor when the control body is uncoupled with the cartridge, and in which the heating element is unpowered and causes a logical low level of the voltage at the second positive conductor when the control body is coupled with the cartridge;
measuring the voltage at the second positive conductor; and
controlling operation of at least one functional element of the aerosol delivery device based on the voltage measured at the second positive conductor.
