Project requires 12V DC supply, all 4 trigger inputs require TTL signal, Relay-1 to Relay-4 inputs connected to D8 To D11 of Arduino digital pins through solder jumpers J1 To J4. 4 Channel Relay Shield for Arduino UNO is a simple and convenient way to interface 4 relays for switching applications in your project. Now you can control relays 1, 2, 3, and 4 in Relay Shield #2 using the Arduino’s 8, 9, 10, and 11 digital I/O pins. When you have uploaded the code to your Arduino/Seeeduino board the motor should run one second, stop for another second and repeat the process indefinitely. /* Arduino Relay Shield Switch ON the Relay connected to D7 for 5S then OFF for 3S, continuously. With relays you can now connect external circuit or devices directly to your Arduino. ARDUINO NANO 33 BLE.

It is possible to control the Relay shield through Arduino/DFRduino using digital IOs with external 7 to 12V supply. Note that the distance between digital pins 7 and 8 is 160 mil (0.16"), not an even multiple of the 100 mil spacing of the other pins.The shield is compatible with all the Arduino boards, 5V and also 3.3V standards.The Arduino 4 Relays Shield allows your Arduino driving high power loads. Very compact design that can fit on top of Arduino UNO. The Shield features four relays, each relay provides 2 pole changeover contacts (NO and NC); in order to increase the current limit of each output the 2 changeover contacts have been put in parallel.

An RTC (Real-Time Clock) module keeps track of the current year, month, day as well as the time, using a single lithium cell even though there is no power to the circuit. 3.Now you can control relays 1, 2, 3, and 4 in Relay Shield #2 using the Arduino’s 8, 9, 10, and 11 digital I/O pins. Relay Shield #1 5V pin is connected to Relay Shield #2 5V pin; Relay Shield #1 Digital Pins 8, 9, 10, and 11, are connected to Relay Shield #2 Digital Pins 7, 6, 5, and 4 respectively. Project requires 12V DC supply, all 4 trigger inputs require TTL signal, Relay-1 to Relay-4 inputs connected to D8 To D11 of Arduino digital pins through solder jumpers J1 To J4.
Project is ideally used for low voltage applications and requires extra care in case of using high voltage AC switching.By continuing to use the site, you agree to the use of cookies. x���[�m��&�c�*�%_����s�'Ӽ�뵁F�z)��J���*��)����� #��^;3�#�N��"e�#�� $�Z�?nܝ7n�w�����?������������?�ۋ�x����Uÿ����o��V�&߹t�ٿ�p7����݄�B�q�����ſ��ޫ��/��[o�r��������?}
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.
5 0 obj Four screw holes allow the Shield to be attached to a surface or case. Bluetooth, Gyroscope and Accelerometer! The DFRobot Relay shield V2.1 is capable of controlling 4 relays.
Relay Shield #1 5V pin is connected to Relay Shield #2 5V pin; Relay Shield #1 Digital Pins 8, 9, 10, and 11, are connected to Relay Shield #2 Digital Pins 7, 6, 5, and 4 respectively. © Electronics-lab.com – 2020, WORK IS LICENCED UNDER CC BY SA 4.0 ��|_?�? With the built in xbee socket, it can be wirelessly controlled via Xbee/bluetooth/WPM. Relay Shield #1 GND pins are connected to Relay Shield #2 GND pins.
