![]() ![]() Put simply, you can now turn on and off lamps, fans, solenoids, and other small appliances that run on up to 250VAC or DC power using any Feather board. It gives you power to control, and control over power. a 12 volt LED light strip that is controlled on/off by the Arduino Board. Description A Feather board without ambition is a Feather board without FeatherWings This is the Power Relay FeatherWing. If we use a 12V power supply we can place 3 LEDs in series with one resistor. peripherals a relay connects a secondary power source to a controller (i.e. Or connect directly to a 12V to 48VDC or even 120VAC circuit. All this is avoided if we use one resistor per LED as shown on the right, this is the way to go. Universal control voltage 3-60VDC or 12-120VAC connects to Arduino, Raspberry Pi, PIC or other micro. 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. Also, the resistor gets the combined current of all LEDs together, which can become too much for a standard 1/4 W resistor, it may get hot, you’ll probably have to use a higher wattage resistor. Although it might work if you try, due to tolerances chances are that one LED will draw more current than the others and they will burn with different brightness. The way shown at the left generally is not a good idea. How to connect multiple LEDs? If we use a 5V DC power supply and if our LEDs have a 3V voltage drop, we can not connect them in series, we need to place them in parallel. They can operate at very high frequencies, which make them suitable as a dimmer for a LED strips (Pulse Width Modulation). ![]() Life expectancy: 100,000 operations 15 amps, 125vac, resistive DC input: 3vdc (3ma) to 12vdv (30ma), terminal block accepts 30-14 AWG wire. AC output: NEMA 5-15R Receptacle, standard 120vac with ground. ![]() It’s an electronic switch, it makes no noise. It gives you power to control, and control over power. Technical Details AC input: NEMA 5-15P Plug, standard 120vac with ground. Arduino FET modules mostly are specified for DC up to 24V 5A.It’s a mechanical switch, it makes an audible click. The relay module can switch AC up to 250V 10A.When to choose a relay, when a FET? Both can be used, but there are some differences: Scroll all the way down for links where these can be bought. (A FET is a special kind of transistor (Field Effect Transistor) that is often used in switching applications). With the IoT Power Relay you can easily control the power going to a device with an Arduino, Raspberry Pi or other single-board computer or microcontroller. One is the relay module which can be had with 1, 2, 4 or 8 relays on a board. A couple of easy to use modules that are capable of switching higher currents are available, tailored for use with the Arduino. ![]()
