Software Arduino Toggle switch This key difference (memory) is what allows you to create a toggle switch in software i.e. by adding memory to a push button switch, you can create an Arduino toggle switch. All you need is a variable associated with the push button input which you invert ...
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...
