Relay Shield V3.0

Introduction

The Relay Shield utilizes four high quality relays and provides NO/NC interfaces that control the load of high

current. Which means it could be a nice solution for controlling devices that couldn’t be directly controlled by

Arduino’s Digital I/Os. Standardized shield form factor enables smoothly connection with the Arduino. The

shield also has four dynamic indicators show the on/off state of each relay.

Model: SLD01101P

This will prevent the relay shield from making contact. Do not operate voltage more than 35V DC.

J1 Interface: COM1- Common pin NC1- Normally Closed. Will be connected with COM1 when RELAY1 pin is set low and disconnected when RELAY1 is high; NO1- Normally Open. Will be connected with COM1 when RELAY 1 pin is set high and disconnected when RELAY1 is low; J2-4 Interface are similar to J1 interface, except that the control ports are RELAY2-RELAY4.

Here we will show you how to use the Relay Shield to control a DC motor. 1. Stack the Relay Shield onto Arduino. And connect Arduino to PC using a USB cable. 2. Connect the DC Motor and Relay Shield as shown below. Use Relay 3 to control the motor. Hardware installation as shown below. Note：We use a lithium battery as the power supply for the motor. Users can select other power sources as well. Of course, a power adapter will be essential when using high-current devices. 3. Restart the Arduino IDE.

// the setup routine runs once when you press reset: void setup() { // declare pin 5 to be an output: pinMode(MotorControl, OUTPUT); } // the loop routine runs over and over again forever: void loop() { digitalWrite(MotorControl,HIGH);// NO3 and COM3 Connected; delay(1000); digitalWrite(MotorControl,LOW);// NO3 and COM3 Disconnected; delay(1000); } When Digital 5 set high, NO3 will be connected with COM3. The motor will work and the 3rd Relay Normally Open Indicator will be lit.
