Relay Arduino Interference at Michelle Baldwin blog

Relay Arduino Interference. Many folks think it’s a voltage problem and try. A relay accomplishes this by using the 5v outputted from an arduino pin to energize the electromagnet which in turn closes an internal, physical switch to turn on or off a higher power circuit. * a relay basically allows a relatively low voltage to easily control higher power circuits. often problems arise with electromagnetic interference (emi) that can cause problems like these: i don't see how the relay for light 1 relay can interfere with the arduino, other that the change in load generating some noise on the 12v. most likely, the interference goes precisely along the power line, where the relay coil and the arduino power supply are combined. i suggest, as a test, you try isolating the arduino from the rest of the devices with a separate supply (battery?). try disconnecting the 2 wires from the nano that go to the 2 float switches, then experiment with (a) leaving pins 4. i'm using a normally closed relay that is switched open by an arduino, and it works perfectly when no 115v is. it’s a common issue when running inductive loads from a arduino controlled relay.
