  • Mike picked up a $10 SainSmart 8 Channel DC 5V Relay Module, hooked it up to an Arduino micro controller (a Raspberry Pi should work, too!) and the next thing you know he's remotely controlling 8 electrical devices... it's like building an 8 channel remote, each relay on the board can handle some serious juice, up to 10A 230V AC, 30V 10A DC. It's super easy to set up. Learn how in the video!

    Cool episode. It would been cool to see how the lights and fan were hooked up and powered. Seeing that could give me more insight as to how the wires are.

    • @diytryin
      @diytryin  10 ปีที่แล้ว +13

      Think of the relay switch as interrupting one of the wires. When it's switched off, it's like you cut the wire.
      For the fan we literally cut one of the fan wires and put one half in the COM (common connection) and one in the NC (normally closed) slots.
      Take a look at this page for a better explanation:

    I like to use solid state relays because they act as a transistor, whatever frequency you give it, it can turn on and off at that frequency, a mechanical relations can only oscillate so much

    @DarkStar851 9 ปีที่แล้ว +8

    Just thought I'd toss this in for anyone interested in toggling a mechanical style relay with any sort of frequency like Michael did with the 40ms delay -- you're going to burn the thing out fairly quickly if you're doing something like that all day long. You should consider a solid state relay (more expensive than these old mechanical ones) for that application. Or a high-power MOSFET (which effectively is all a solid state relay is, just without the heatsink and terminal block attached)

    basic coding etiquette: if someone posts their code online to share it is perfectly acceptable to use some, or all of their code in your own code; however, if you share any code that has other people's work in it you should credit them just like any other work.

    @tuckervaldeze7179 9 ปีที่แล้ว

    I know this video is 2 months old but I purchased a Sainsmart 8 channel relay board for my arduino and i was wanting to know if the relay is Active LOW or Active HIGH, and what you used as a power supply to isolate the arduino and relay board, I can't seem to find a straight answer anywhere, and I watched your video and thought I might get a straight answer here.

  • @ExStaticBass
    @ExStaticBass 6 ปีที่แล้ว

    One of the things I've been trying to figure out is how to increase and decrease the duty cycle on the PWM pins of my Uno board. The goal is to make some DIY signage that changes brightness with an LDR so that it's as visible in bright light as it is in dimly lit situations whereas it can also save power. I've figured out how code for the sine change from let's say "open" to "closed" using some transistors and a diode AND gate network. The brightness thing with the LDR though is a little harder to wrap my head around. Little help?

  • @melannieworld

    Love the energy... I've been looking around for some advice. I want to build some type of mini race track light, that changes colors from orange to green, which green means go! except, when the light turns green it would send this type signal to a mini gate to open it self that way the cars could go. Any idea?>

  • @jeremyhenderson163
    @jeremyhenderson163 4 ปีที่แล้ว

    :) Thank you for your videos, great stuff. What would be a good basic automatic relay circuit to make load A2 turn on when load A1 shuts off?

    • @jeremyhenderson163
      @jeremyhenderson163 4 ปีที่แล้ว

      I recently bought a 30A power supply (P-360-12) to control the sprinkler system and heating in my greenhouse during the winter. The stat sheet ( www.wlgled.com/estaticos/media/producto-pdf/8PS120360DCU.pdf ) said "2) Do not overload, also avoid free of load while a power supply is powered on, keep proper loading" so now I'm concerned about damaging the power supply in the time that both the automatic heating (12v-16ish A) and watering (12v-2A) circuits disconnect. So I was thinking of adding another load (12v-15A) that would only turn on when the heating circuit disconnects (As it will be the most used load, as well as the biggest.). I'd prefer to lean away from Arduino as I am currently a novice and haven't yet ventured into it, any suggestions?

    Hello guys,
    Thnx a lot for your great TH-cam, It means a lot if you char what you’re good in, so we can learn from each other. I hope you have time for a small simple question. Is there power on your relay coil when the NO contact is closed (when you’re hooked up appliance is on) like a standard relay or does it gets a pulse each time you switch on and off you’re appliance?
    Greats

    hi
    i want to simulate a push button using bluetooth from my phone on a music system
    what i want to achieve by doing this is when we power on the music system(by using WiFi enabled Sockets), by default it starts in aux mode
    by using mobile with bluetooth it changes it from aux to bluetooth mode so we can connect it with mobile and play music at scheduled time by using Tasker app
    so we dont have to physically push any button
    thanks

    I have the fan hooked up to the relay. The relay is switching on and off and directed in the code, but the fan does not turn on. When I fan wires directly into a house outlet it powers up. What am I doing incorrectly?

    hmmmm. Maybe I should get my hands on one of those. Could be fun to write some code for. Not sure what I would use it for right now though =)
