The shield is compatible with all the Arduino boards, 5V and also 3.3V standards. PC Arduino: Sends data (command) from PC to Arduino. This is usually used for debugging and monitoring. It is used for two purposes: Arduino PC: Receives data from Arduino and display data on screen. 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. Serial Monitor is one of the tools in Arduino IDE. Four screw holes allow the Shield to be attached to a surface or case. The maximum length and width of the 4 Relays Shield PCB are 2.7 and 2.1 inches respectively. Both connect to the same TWI interface to allow you to create a chain of TWI devices. 2 TinkerKit TWI: these connectors (4-pin in white) are routed on the Arduino TWI interface.2 TinkerKit Outputs: OUT5 and OUT6 (in orange), these connectors are routed to the Arduino PWM outputs on pins 5 and 6.Then, LCD displays the data on the screen. LCD stores the received data in the data resistor since the RS pin is HIGH. 2 TinkerKit Inputs: IN2 and IN3 (in white), these connectors are routed to the Arduino A2 and A3 analog input pins. The process of sending data (to be displayed) to LCD: Arduino sets RS pin to HIGH (to select data register) Arduino writes data to D4 D7 pins (data bus).Connecting TinkerKit modules can simplify the creation of a project or a prototype. Use it to enhance the IoT features of your MKR1000, as well as store data coming from the web or sensors read by your board Theres also a small prototyping area for soldering components. We just do the basic function, you can change it according to your creativity. The source code is to control the relay by using timer. Upload the source code into your Arduino code that we give. The relays are controlled by the following Arduino board pins: Relay 1 = 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. The Arduino MKR SD Proto Shield allows you to easily connect an SD card to your MKR form factor board. Step 2: Upload the Source Code Into Your Arduino UNO. The shield doesn't need external power: it will be provided by the base board, through the 5V and 3.3V pins of the Arduino board used as base. Single pole chargeover contact maximum 30 V DC 2A PDF Descriptionġ40 mA (with all releays on, about 35 mA each) The Arduino 4 Relays Shield is open-source hardware! You can build your own board using the following files:ĮAGLE FILES IN.
