text: If not, the relay is still effectively open (for instance, by the above rules): it is easy to forge e-mail header and envelope information, it is considerably harder to successfully forge an IP address in a TCP/IP transaction because of the three-way handshake that occurs as a connection is started.
text: This protection will suppress noise and prevent the generation of carbon at the contact surface when the relay is opened.
text: When the relay does not receive any power, it is off and the Normally Open (NO) contact pin remains opens.
text: NO (Normally Open): the normally open configuration works the other way around: the relay is always open, so the circuit is broken unless you send a signal from the Arduino to close the circuit.
text: If the relay is instead placed between the load and ground, the circuit will still work the same, but when the relay is open, the load will still be directly connected to the power supply.
text: If it is normally open, the arm of the switch is held away from the contact with a spring when the relay is off and the electromagnet pulls the arm to make contact and close the switch when the relay is turned on.
text: Or by feeding the stepping contact with an endless pulse train via a relay, and controlling the relay from the switch's own output, it can be made to automatically hunt for the first unpowered line (or powered, depending on whether the relay is normally open or normally closed).
text: When the relay is open, the current is zero.
text: Bounce The switch contacts bounce when the relay is opened or closed, so you do not get a clean electrical edge.
text: Once the relay is opened by flipping the switch to turn the light on, a signal is sent to tell the light to turn on.
text: When someone is calling or an individual picks up the phone to call someone, the relay is opened, allowing the call to be transmitted or received.
