The shield has 4 buttons (S1-S4), so that a connection test is also possible without uploaded sketch. The shield has room to hold an XBee device. 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. Arudino Uno/Leonardo/Seeeduino compatible; Other board or microcontroller via jumper cables Relays are literally just electrically actuated switches, so you can connect them pretty much anywhere you would use a switch. With a relay circuits can be switched with a different voltage than is necessary for the operation of the Arduino. By the end of this tutorial, you should be able to control any electronics appliances with your Arduino using a relay module. Arduino … Arduino GND pin - Relay module GND pin. Serial.begin(9600);// setup Serial Monitor to display information, pinMode(relay1, OUTPUT);// connected to Relay 1, pinMode(relay2, OUTPUT);// connected to Relay 2, pinMode(relay3, OUTPUT);// connected to Relay 3, pinMode(relay4, OUTPUT);// connected to Relay 4, digitalWrite(relay1,HIGH);// turn relay 1 ON, delay(3000);// keep in relay 1 On for 3 seconds, digitalWrite(relay1, LOW);// turn relay 1 OFF, delay(3000);// keep in relay 1 OFF for 3 seconds. 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. In this example we will connect a simple load such as a led at the output of the relay and will control it by using the Arduino. With this "Hello World"-example I turn the Relay1 on Default D2 for 3 seconds on and off. The Arduino can be programmed to turn on the 4 channel relay module when a certain event occurs, for example when the temperature of a thermistor gets higher than 30° C. Or when the resistance of a photoresistor drops below 400 Ohms. It can be directly controlled by Arduino/Seeeduino through digital IOs with external 9V supply. This 4 channel relay shield for Arduino is ideal for easily controlling multiple devices that run higher than 5V (Motors, LED strips, etc).
