Arduino relay shield 230v how to#
Here is a simple picture showing how to connect the LED to the relay shield Connecting TinkerKit modules can simplify the creation of a project or a prototype.
NO1 (Normally Open): This terminal will be connected to COM1 when the RELAY1 control pin (Digital 7 I/O pin) is set high and disconnected when the RELAY1 control pin is set low. 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. NC1 (Normally Closed): This terminal will be connected to COM1 when the RELAY1 control pin (Digital 7 I/O pin) is set low and disconnected when the RELAY1 control pin is set high. In this example we will show how to use one of the relays on the shield to control an LED by switching it on and off.ĬOM1 (Common Pin) : The relay pin controlled from the digital pin. Opening and closing time per minute: 30 times Įvery channel maximum convert voltage: AC 125V / DC 24V Įvery channel maximum converts current: 3A Application High performance expansion board Please avoid the green terminal short-circuit by the housing as connecting with Arduino UNO main board
Relay Shield is a small current signal control module can achieve single chip to control large power deviceĬan be plug to the main board which is compatible with Arduino Ĥ-channel relay stand Arduino Shield interface ĭriven by 5V / 3.3V normally open contact close Relay Shield v0.9b 5V 4-Channel Relay Module for Arduino – (Works with official Arduino Boards) – $9.73 If (client.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.

Arduino relay shield 230v code#
The code for NodeMCU is compatible with v2 Amica and v3 Lolin.ĭemo for testing: (Slovak language sorry, i will translate your sketch/php files to your language) It is best to buy an 8-channel relay for this project, it is tested under both boards and works great.Ĭodes for Arduino are compatible with any Arduino, where W5100 Ethernet shiled can be connected. To the code for Arduino / NodeMCU I will give the code for the part of the web, the scheme for the relay connection and the relays themselves. Ethernet for Arduino to HTTP website and NodeMCU with wifi connectivity to HTTPS page.
Suitable for outdoor lighting, remote administration, intelligent house etc. Control relay over the internet from the comfort of work or home.
