Arduino pir sensor led and buzzer code | pir motion sensor projects

In the Arduino pir motion sensor project, We start with basic whenever pir sensor detect a hand gesture or motion then the LED is blinking and beep a Buzzer. " arduino pir sensor "
We will learn about how pir sensor( HC-sr501 ) work and we can control 230v bulb with hand gesture by using pir sensor, relay, and Arduino. Using Arduino to get a signal from the pir sensor and then send a signal to relay to switch a load and turn on the 230v blub.

Thank you sir. It worked just fine for me . Please take care.

[maceojesson]

c est une des meilleures vidéos d arduino! elle est parfaite...

[Qeel_K]

1:31 where can you buy that buzzer gnd

[malcolmmillena]

Hi I'm just curious and I am also new to making an Arduino project, what is that big block you were using in the PIR motion sensor and what's the purpose on that?

[usechegod]

What do I do if loading the code activates and stays ringing but never turns off

[francismarievictoriamendoz]

ive watched thisl ike 5 times now WHY WONT IT WORK AAAA

[dheydreamin]

great codes! it works with no problem. however, when i add nrf24l01 module to it (the setup in the video being the transmitter) it doesn't detect motion and the led and buzzers are not working. is there anything else i could do?

[HARISHARIS-drjh]

Does this whole circuit run on a 12v battery?

[BAECAkshayrenake]

on which software you are running this Arduino code, plz help

[burakk.]

sir In my code, low, high, input, output texts appear colorless and my circuit did not work. I think my library is missing where can I find it?

[Nihal_Pandey]

its working but buzzer are regular sounding please tell me solution of this problem

[_xitkro_shokhibulakmal]

bang punya saya gaada gerakan kok nyala sendiri ya buzzer nya?

[jhonericcoz]

Hi! is it possible that if the sensor sensed gesture it triggers the LED to On first and if f the gesture is in repeatable state after 5 sec the buzzer will be on as well. and there is a scenario that the sensor sensed gesture let's say for just only 1 sec it triggers the LED only but not the buzzer? please help me for this sir. 🙏🙏

[DennisPangilinan-hh]

why does the buzzer keep chirping? what if it just buzzes and then stops after a few seconds, then it just buzzes again when something is detected.

[kashishharyani]

What is the prize of the products which are used in this project? Can any one of you help...

[AyeshaMohammad-wy]

We don't have gnd buzzer is it necessary

[GoalCoder]

good, but I want it to make the sound if the motion is not moved for 5 seconds

[tokioso]

@mr projectsoPedia can i use speaker (my audio) in place of buzzer..

[baddrakachaminda]

Hi is it okay if I use a long bread board and any led?

[JEDSaje]

Would it be possible to have the motion sensor trigger a hotkey on a computer if still plugged in?
