Therefore, mostly because of my choice of Led strip, I use a DC of 5V/2A. The Led Strip supports 5V (its a WS2812B). You will need tools such as a soldering iron, solder, wire cutters, etc. The concept is simple : when we detect a motion, we switch on the relay, which gives power to the Led strip, and turn the leds on. This kit does not include the tools you will need to assemble the circuit. You will get a schematic and all of the parts to assemble a working unit. You can select from 1 to 4 Relays, the default selection is one Relay. NO: Normally open 120-240V terminal C: Common terminal Ground: Connects to the ground pin on the Arduino 5V Vcc: Connects the Arduino’s 5V pin Signal: Carries the trigger signal from the Arduino that activates the relay Inside the relay is a 120-240V switch that’s connected to an electromagnet. This is one of the first practical applications for Arduino that you will find. This kit is now offered with a "Built & Tested" option for those that do not want to build it themselves. Have them alternate back and forth for a nice effect. You can control many different 120 VAC devices, such as your Christmas lights, sprinkler system, garage door, etc with the program you write using your Arduino UNO. This means that the circuit can either turn devices ON for a set time period or turn those devices OFF for a set time period. The available contacts are the Common (COM), NO (Normally Open) and NC (Normally Closed). Each set of Relay contacts are available at a dedicated 3-pin screw terminal. The Relays are an 833H series SPDT relay with Form 1C contacts rated for 7 Amps 250VAC. The required external 12vdc power supply is not included. They do not need to be connected to the computer once it is programmed. ![]() ![]() ![]() This means you can write your program, load it into the Arduino, and then relocate both units to anywhere that you need. This 12vdc is also connected to the Arduino VIN input so that both units can be powered by the 12vdc coming in. There is a 2-pin screw terminal for an external 12vdc to power the relay. The Relay is controlled by the Arduino Digital outputs and the DIP Switches are connected to the Arduino Analog inputs.

This relay kit will plug directly on top of your Arduino UNO. Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal. It also includes a 2-position DIP Switch so that you can add some options to your program. It consists of an Arduino-compatible Shield with a 12v Relay. This is the Arduino-Compatible Relay Shield PCB Kit. ![]()
