We will connect a servo motor and a pushbutton switch to the Uno. I have also wired in a 6-volt power supply for the servo, as I’m not fond of using the Uno 5-volt output for this. Here is the wiring diagram for our first device: Joining the IoT Cloud Our device, the Uno bo...

As we will be using the state of the pushbutton as input for Arduino, there is no need to support "click" or "double click" events. It is up to the Arduino program running in the simulation to decide how to act upon the state of the button, and physical buttons do not generate cli...
