Introducing IoT buttons
Toward the end of the animated movie WALL-E (2008), Captain McCrea battles against the AI autopilot to regain control of the Axiom spaceship by pushing a big blue button. This results in the massive Axiom starting its hyperjump on a return to Earth. The single button in sci-fi often stands as a beacon of innovation, a dramatic tool that accentuates pivotal moments. In the case of WALL-E, this button surpasses a simple one-action result, such as sounding a buzzer, and instead carries the weight of humanity’s future, triggering a series of actions that eventually lead to the redemption and rebirth of both mankind and Earth.
In this chapter, we will build our own powerful button, although not one with the power of the blue button from WALL-E. Our button will, however, introduce us to the world of IoT buttons where single actions can trigger a series of automated tasks – in our case, interacting with the IoT alarm module we built in the last chapter...
