1. A blade control assembly for a lawnmower including a power source and a blade rotatably driven by the power source, the blade control assembly comprising:
a controller configured to,
selectively transition between a sleep mode and an operational mode,
transition from the sleep mode to the operational mode when the controller receives a first ON signal,
cause the power source to transition from an idle state in which the blade is stopped to a driving state in which the power source rotationally drives the blade when the controller receives the first ON signal and a second ON signal,
continue signaling the power source to drive the blade if the first ON signal terminates while receiving the second ON signal,
cause the power source to stop rotation of the blade and cause the power source to transition to the idle state after the second ON signal terminates, and
transition from the operational mode to the sleep mode after the second ON signal terminates.
