The shield provides two relays (Datasheet) called RELAY1 and RELAY2 commanded by pin 1 and pin 2 respectively. 4 Channel Relay Shield for Arduino UNO is a simple and convenient way to interface 4 relays for switching applications in your project. This is a simple tutorial, remote control over the LAN. 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. You can also measure the motor current absorption of each motor, among other features. Almost any sensor can be used to trigger the relay to turn on or off. Your email address will not be published. After designing the PCB, we can order the PCB samples by their low cost PCB fabrication services. The bottom view of the wiring diagram for this relay is shown here: Bottom View of the JRC-23F Relay. Simply plug the shield into your Espruino board. It also provides NO/NC interfaces and a shield form factor for the simple connection to the Arduino … These shields are extremely easy to use, so no code library is currently provided. 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. you would use a switch. It is possible to control the Relay shield through Arduino/DFRduino using digital IOs with external 7 to 12V supply. Note: … And optocoupler will be triggered by the active LOW signal. The four relays each have NC and NO pole changeovers and are set in parallel to amplify current outputs. This makes prototyping with Arduino plug and play. In this DIY project we make a 3-Channel Arduino Relay Shield Circuit for relay based applications. Module features are as follows: 1. The shield consists of four relays and four LED indicators. It can be directly controlled by Arduino/Seeeduino through digital IO. The Arduino digital I/O pins cannot bear the high current due to its voltage and current limits. Each relay has a 3-wire terminal block which allows the relay to be used both in the "normally open" mode and in the "normally closed" mode. To control it, I used HTTP and JSON. We have connected all 3 relays with Arduino at 7, 9, and 12 pins (RLY1, RLY2, and RLY3).
