In this video, Zahraa explains pushbuttons. Pushbuttons are considered an input when connecting them to Arduino. Learn about normally open and normally closed pushbuttons and why they are considered inputs to the Arduino board.
- [Zahraa] Pushbuttons and switches…come in different sizes and shapes used in many applications…with Arduino to provide an input signal.…A pushbutton is a component that connects two points…in a circuit when you press it.…Simply, an elliptical component that connects two pieces…of metal together, allowing a current to pass.…This is a simple electrical circuit.…A path for current is made when the pushbutton is pressed…and the current path is broken when the pushbutton is open.…
A pushbutton is either a momentary or maintained switch.…Momentary switches only remain in their own state…when they are being pressed.…There are two main types of pushbutton arrangements…normally open and normally closed.…Normally open pushbutton means a pushbutton switch…that must be activated or pressed…to make the connection between its terminals.…When the pushbutton is not being pressed,…the connection between its terminals is broken.…
Normally closed pushbutton, on the other hand,…is a pushbutton switch that must be activated,…pressed to break the connection between its terminals.…
