How to Set Up a 5V Relay on the ArduinoSince the Arduino operates at 5V it can’t control these higher voltage devices directly, but you can use a 5V relay to switch the 120-240V current and use the Arduino to control the relay. The Arduino can be programmed to turn on the relay when a certain event occurs, for example when the temperature of a thermistor gets higher than 30°C.
Guide for Relay Module with Arduino | Random Nerd TutorialsThat means if you send a LOW signal from the Arduino, the relay turns on, and if you send a HIGH signal, the relay turns off; it works with inverted logic. Set the PIR motion sensor as an interrupt: pinMode(PIRInterrupt, INPUT); // Triggers detectMotion function on rising mode to turn the relay on, if the condition is met attachInterrupt(digitalPinToInterrupt(PIRInterrupt), detectMotion, RISING);

Relay Tutorial for Arduino, ESP8266 and ESP32Note that you can control as many relays as digital and also analog pins your microcontroller has. For the digital pins you have to set the pins HIGH and the analog pins to 255 to activate the relay. The following picture shows the wiring between the most used Arduino, ESP8266 and ESP32 microcontroller and a relay module.
Arduino relay shield tutorialThe relays are controlled by the following Arduino board pins: Relay 1 = Arduino pin 4 Relay 2 = Arduino pin 7 Relay 3 = Arduino pin 8 Relay 4 = Arduino pin 12 The shield features several TinkerKit input/output and communication interfaces. Connecting TinkerKit modules can simplify the creation of a project or a prototype.
Driving a Relay With an Arduino : 9 StepsYou can use a 5V relay to switch the 120-240V current and use the Arduino to control the relay. * A relay basically allows a relatively low voltage to easily control higher power circuits. 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.

How to use 5V Relay on ArduinoArduino is a microcontroller based prototyping board that runs on small DC power. A Relay is a device that helps microcontrollers (or microcontroller based boards) like Arduino to switch on or off different household appliances like motors, lights, water heaters, television and fans etc. Today, Arduino is being used for a wide range of applications […]
