Hello, I have explained this line by line and what it does. So if you play the code section 2,3 or more time you should easily understand and turn the same relay on.

it should work the same, (connect new sensor's ground and power pins) and just connect the signal to another pin number, and in your code, you test for that pin number too (besides the previous sensor's pin).

Hi Robojax. The pir works fine with arduino with your code, however I don't understand why it is 'digitalWrite LOW' to turn on the relay and the opposite to turn off? When I use the pir with the relay running from 5v dc supply (not through arduino)then the light is always on. Do you know why it is like that, looks like the pir doesn't trigger. Thanks

Hi Love your video and explanation I would like to simply turn on and off a 5V DC laser light that has a simple on off switch which I would like to control by the Audrino & PIR sensor Can it be done without a relay ? Can you suggest a solution ?
@robojax 2 жыл бұрын
Hi, I don't know for what reason you want to avoid using relay but we need a switch to turn ON/OFF the load. If your laser light needs up to 30mA maximum yes you could use Arduino without relay. if you don't like relay, then you can use solid-state switch like mosfet shown here kzfaq.info/get/bejne/Z52mpK-nmpachas.html

Hey, great video btw. I used exactly what you used and it works great. I do have some concerns though: is this risky at all? I intend to keep it running 24/7. Will the arduino overheat or the relay have problems ? because I heard the relays tend to fire up frequently on voltage change and such? Do I have to worry? It's inside an electrical box right outside the house with all the components inside that box.
@robojax 3 жыл бұрын
Hey, I have not tested the reliability of components. there are tones of different brands producing components. But for Arduino and relay you can add 200mA fuse on the 5V power line so would never allow extra current that might cause fire. Try get relay from Digikey or some other reliable store and make your own module. here is how you can drive a 5V relay using Arduino kzfaq.info/get/bejne/hJOWec5mlqvGaKc.html Arduino itself should be good quality if you purchase Authentic Arduino from Amazon amzn.to/2KApAwK it should be more reliable. Good luck and stay safe.
@goldenice9283 3 жыл бұрын
@@robojax Thanks for replying, I'm sorry I'm not really good with these stuff. Does the fuse have to be 200mA? because the least I could find from local stores are 1A. And what exactly causes the fire or what is more risky should I say? the AC 220V on the relay connected to the outlet or the 5V from Arduino?

These relays are used widely in lots of electronic devices.

I wonder if you can help (great video thanks!) I have this sensor but would like a small unit without the arduino. I have it linked with simple single LED and transistor to test. It's working.. but whatever I set the RIGHT wheel for delay to, it keeps randomly lighting with gaps in power. So it will light for 3 seconds, then stop, then light again even though I keep moving it switches off. ?
@robojax 5 жыл бұрын
You are welcome. Please watch the video again. There is jumper and two controller. You have experiment and find solution for yourself. The jumper is very important. Have patience and play with it and write down on paper what you did in each step and then compare the results.. this device is very good and it should work for almost any situation. When finding and testing, your single motion will change everything so make sure you sty still if you want no trigger happen.

So If you want that relay to stay on for 10 seconds you need to increase delay time, but when loop gets to that delay it cant trigger relay because of that delay...
@robojax 3 жыл бұрын
first if you want it to stay for 10 seconds, then all other triggers should be ignored. Isn't it? Yes there is solutions. We can use millis() which will not keep the loop waiting. see my two videos in that topic kzfaq.infosearch?query=millis
