Hii ! Just to clarify, really need ur help? For my project, I'm not using ac bulb but i'm using Led strip WS2812B for smart aquarium (fish tank) as in i want it when turn on, its dark and when turn off, it's not dark. so can this code and wiring works for my led strip ? and also what are the changes of code?
Relay is a mechanical switch . It works for anything if you respect the power earring. Here see what is inside relay ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-N-fFk51Eb8s.html
Can we connect photosensitive module and relay module without arduino,if yes which pin of photosensitive module should be connected to relay module in.AO or DO pin?
Hi, Yes you can. Depending on the relay module types, you may get reverse effect. when you want to turn ON it may be OFF and when you want it OFF, it might be ON. But there is no timer control. if you want to turn ON or OFF for certain time, then you may use one of the timer modules here ru-vid.comsearch?query=timer
Hi sir plz help me for this I want to make a project on dc motor. I want that if i puch 1 time push button then motor will run for 5 sec. And every time i push button then moror will run for 5 sec. How i do this I have relay module aurdino uno and dc motor with push button. Plz send me a programming for this and circuit diagram also. Plz plz plz🙏🙏🙏
Can I use this light sensor to measure light frequency with an oscilloscope.? is it just supply 5v power and gnd, but which pins of the 4 shall I use for the scopes black and red crocodile clip if I wanna get feedback from the sensor to see the frequency of a screen refresh rate.? I would reckon that light-sensor would be able to registrate fast light pulses, and give that waveform on the scopes, but how to hook it up?
Hey ! This was a very informative video ! Thanks a lot ! I had a question, if we set digital as true to adjust sensitivity using potentiometer, then do we need to connect the Analog out from the LDR to arduino ? Because I have a LDR module with only DO, hence I wanted clarification whether we can only connect to DO, set digital as true and control sensitivity with potentiometer, without any change in the advanced code. Keep up the good job :)
Hi , it seems you may have missed or skipped the video. you are getting the opposite. please watch. Digital means ON or OFF. there is not in between values to adjust.
@@robojax Yes, I get that, but my doubt is whether the connection with AO is necessary for the advanced part with digital set as true and sensitivity is with potentiometer. Basically can the advanced code be run on arduino nano without connecting AO and setting digital as true
Hi Robojax! I want to use you cod to control a motor for 3 seconds when it's dark (evening) and the same thing when is light, in the morning for 3 seconds (same command). Can you help me with cod? I'm not beginner but is the first project with Arduino. Thanks!
Hi, you are asking something that needs a separate project. perhaps you start from here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Mbb2xa1WcRM.html
sir iwant to use as soler tracker but it wil on when dark i wat to know if it is on sun than it work how can be it possible simple i want soler tracker circuit plz
Solar tracker from the name we know it should track the sun. It needs a little work. Not that simple. It needs motor, actuator, controllers and light sensors with code. I have it on my "to do" list. But don't know when. Thanks Ahmad from Canada.
Connect them to 5V. if your arduino doesn't have 2 tV, then create additional 5V. Watch this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Vmrmp7reHOY.html no schematic. I have explained wring. If you need it then draw it.
I just played the video . Please watch 1:56 where I have explained the light sensor and you know what each pin is going. At 3:20 Relay is explained. You can click on the time 1:56 to jump directly.
I spent time to watch the video and replied. this is not nice to NOT relay. if someone takes time to do something for you, at least just acknowledge it.
Use this instead: Blackt Electrotech BT31P2 230Volt Auto Day/Night on and off Photocell LDR Sensor Water Proof Olive Wood Lighting Switch (White) www.amazon.in/dp/B01KMAQLB4/ref=cm_sw_r_cp_apa_i_-StwDbZJ23TDR
@@peterjones3879 Yeah it can. You just have to change the direction of the current. In my case, I use the motor head of a drill. For the time now I just use a clock set for an entire year. It's pretty reliable.
I believe that is what I've shown in this tutorial. if you want to reverse the behavior, just change HIGH to LOW and LOW to HIGH in code where it says digitalWrite(....
You don’t need it. This is for learning. First hardware is fully explained and when later I mention the pin name you would know it. So if you watch it full, you don’t need diagram.
Hello, if you search for "Arduino Light sensor" you will get very high quality resolution image where you can see all components. just go to google image search .
