Relay Module interfacing with Arduino – Arduino Relay Module
The Arduino 4 Relays Shield is a solution for driving high power loads that cannot be controlled by Arduino's digital IOs, due to the current and voltage limits of the controller. The Shield features four relays, each relay provides 2 pole changeover contacts (NO and NC);

Arduino 4 RELAYS SHIELD - mediadigikeycom
Note that the true and false constants are typed in lowercase unlike HIGH, LOW, INPUT, and OUTPUT. Defining Pin Levels: HIGH and LOW. Arduino (ATmega) pins configured as INPUT with pinMode() are said to be in a high-impedance state.
How to Use Relays to Control High-Voltage Circuits with an
So for either board, connect the relay GND to one of Arduino's GND pins and the relay 5V or Arduino's 5V pin and the relay IN to one of Arduino digital outputs, say D4. Then when the digital output, D4, is High the relay will operate.
Arduino Relay Control Tutorial with Code and Circuit Diagram
Project: Controlling High-Voltage Circuits with a Relay and an Arduino In this tutorial, we will turn on a 12V motor using a relay. An optocoupler is added to provide even more isolation between the Arduino and the high-power load.
Controlling AC Light Using Arduino With Relay Module
This is a HIGH level trigger relay,apply to Arduino and Raspberry Pi. Relays are suitable for driving high power electronic devices such as lights, electric fans and air condition. A relay can be used to control high voltages with a low voltage by connecting it to an MCU.
Arduino 4 Channel Relay Module - Henry's Bench
Hello friends! I'm Ostin,I ll demonstrate how to control a AC light with Arduino using relay module. It is a simple project and also very dangerous as we are going to deal with high voltage 220v .
Home Automation - How to Add Relays to Arduino: 9 Steps
Arduino Control Relay Schematic. How does the circuit works. When the button is pressed the Arduino board will put pin 2 in HIGH state, meaning 5V on pin 2. This voltage is used to drive the transistor that will switch ON the relay and the load (in our case the fan) will be powered from the main power supply.
