For one of my hobby projects I would like to use: Wemos D1 mini pro (schematic) Wemos D1 Relay Shield (schematic) to control the 24V (19W) mist maker. Arduino Relay Shield Schematic 54 And if you are a student or an educator, you could get PCB for free, read this article to find out how: Free PCBs and Discounts for Students and Educators with PCBWay’s Sponsorship Program. 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 price of standards electronic components are relatively cheap. The digital inputs and relay outputs are equipped with an LED that indicates the status. Looking at the schematic, it looks like using the DS18B20 temperature sensor (and the infrared receiver module) requires a bit of research. By default the relays are controlled by D2, D7, D8 and D10. Arduino schematics may not be available in Altium Designer’s file format, but the import and conversion tools still allow you to import schematics and begin creating your own board. Some shields also require a connection to the Arduino’s ICSP header (the 2×3 programming header on the end). We routed the traces on Top layer (Red colour) and Bottom layer (Blue colour). Under local CAM jobs, select the sfe-gerb274x.cam, To generate, click on Process Job, and then Specify the folder. SunFounder 5V 8 Channel Relay Shield Module for Arduino R3 2560 1280 ARM PIC AVR STM32 Raspberry Pi 3, 2 Model B & B+ 4.6 out of 5 stars 615. Download the project files including the Eagle based schema and board design: 1. You can’t make them yourself. ARDUINO. We used the Sparkfun EAGLE libraries, you can get the Arduino board under Boards – SparkFun. 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. PCB design in EAGLE is a two-step process. 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. Double Relay Shield with only one Arduino board schematic. You can complete your order online at this link: Below on figure 6 is the Complete Student Companion Easy Relay 1 Shield with Components. . Three-pin Header Connector CN1 and CN2 provided to connect the Load. Arduino Control Relay Schematic. The file is zipped, you will need to unzip it (Download a free version of the Winzip utility to unzip files). There is also an easier way to generate Gerber files from PCBWay, the company we use to manufacture our Printed Circuit Boards. There are many PCB companies in the world that can make you good quality PCBs, but we need one that can produce cheap boards of high quality on small orders because the first batch of any project is likely be of small quantity. 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. From the schematic editor click the Generate/Switch to Board command in the toolbar or Switch to Board under the File menu. Only four Arduino Digital I/O pins, pins 4-7, are required to control the four different relays. The main difference between them is that the UNO board is presented in PDIP (Plastic Dual-In-line Package) form with 30 pins and Nano is available in TQFP (plastic quad flat pack) with 32 pins. Figure 1 below shows the Relay PCB we received form PCBWay. Page 1 of 1 Start over Page 1 of 1 . This will prompt to create a new board based on the schematic when switching to board from the first time. This is a practical tutorial, we’re gonna build a fully working complete Arduino Relay shield, we’re gonna go through all the steps, we’ll start from scratch explaining and simulating the circuit diagram in Proteus, then we’re gonna create a Printed circuit Board with Eagle but any PCB design software can also be used, then we’re gonna generate the manufacturing files to manufacture the PCB with PCBWay our favorite low cost PCB manufacturing company and finally were’re gonna test the operation of the shield with a simple arduino sketch. Please read this article to learn more about PCBWay: Low Cost PCB Prototype and Assembly with PCBWay. Hardware installation as shown below. You can get 10 high quality PCBs (size: 100mm x 100mm or smaller) for just $5 USD. MKR NB 1500. Relay module for Arduino is one of the most powerful application for Arduino as it can be used to control both A.C and D.C devices by simply controlling the relay by giving 5V. Connect the DC motor and Relay Shield as shown in the schematic and figure below: The external power supply in the figure above can be a battery or power supply. Click on the CAM processor icon on the toolbar. To add a schematic to a project folder, right-click your project folder, hover over “New” and select “Schematic”. 24 VDC / 5A Once you import the schematics, you can start editing the schematic sheets to add new components and functions. Give it a meaningful name. Basic Arduino relay shield example The Relay Shield features four high quality relays and provides NO/NC interfaces, four dynamic LED indicators to show the on/off state of each relay, and the standardized shield form factor to provide a smooth connection to Arduino compatible boards. The Relay Shield utilizes four high quality relays and provides NO/NC interfaces that control the load of high current. First we’re gonna design the schematic, then lay out the board based on the schematic. "Arduino" name and logo are trademarks registered by Arduino S.r.l. How does the circuit works. MKR GSM 1400. In this Arduino relay tutorial, I will show you how to use a relay with microcontrollers. Any PCB Schematic design software can be used. You can pick between these solder mask colours at no extra cost: Green, Red, Yellow, Blue, white and Black. Digital 4 â controls RELAY4âs COM4 pin (located in J4), Digital 5 â controls RELAY3âs COM3 pin (located in J3), Digital 6 â controls RELAY2âs COM2 pin (located in J2), Digital 7 â controls RELAY1âs COM1 pin (located in J1), Relay Shield #1 GND pin is connected to Relay Shield #2 GND pin, Relay Shield #1 5V pin is connected to Relay Shield #2 5V pin.

We routed the traces on Top layer (Red colour) and Bottom layer (Blue colour). CAUTION: RISK OF ELECTRIC SHOCK! in Italy, in the European Union and in other countries of the world. Customers who bought this item also bought. 1.Stack the Relay Shield onto the Arduino development board. The circuit diagram is very simple: Add Tip Ask Question Comment Download. The last step in PCB design is to manufacture the actual board, even though you can do it yourself, this is a simple board after all, but for rapid prototyping or for commercial products it’s always a must to use specialized reputable PCB manufacturer instead of doing it yourself. We also added some Text on Top and Bottom Silk layers. Arduino Relay Shield Schematic - Free download as PDF File (.pdf), Text File (.txt) or view presentation slides online. The Relay Shield is an Arduino compatible smart module with 4 mechanical relays providing an easy way to control high voltage. From the schematic editor click the Generate/Switch to Board command in the toolbar or Switch to Board under the File menu. One of those companies we can recommend is PCBWay. RELAYS SHIELD. The relay is connected to D7, to turn it ON, just send a high to that pin and to turn if off , just send a LOW. The MKR Relay Protoshield allows you to easily add relays to your MKR board based project.. The LED D1 will switch when the relay is energized.
