well explained, thank you. Most Arduino users would be at lost how to make these modules work in the real world without arduino lol. I like that you took the extra minute or two to explain how this module could be hooked up without arduino. I like using arduino for experimentation and design, then go to a actual protocol for a device that will actually be used. The explosion of modules that have become available is incredible! Sure hope people move past arduino to designing their own devices from scratch!

sir if we remove usb connection from aeduino after upload the program / code and supply 9 V then what. 2nd point is I except a vedio from u on how bipolar stepper, arduino and controler driver with a code to drive the motors forward revers and with specific angle. Hope you will helps me. all vedios are so good, thanku

does it still detect motion if the sensor itself is in motion? i.e. if you put it on a robotic hand and move the robotic hand

@robojax 4 жыл бұрын

No. As soon as object or the sensor moves, it will turn ON.

@orzzatx6816 4 жыл бұрын

Sir, can we change the code so that to make the sensor keep sending signal eventhough the hand keep in the same position?

@robojax 4 жыл бұрын

I did not understand the role of "hand" here. Perhaps I forgot what is in the video. But if you want to keep something ON or OFF when it detect the motion, here is my video kzfaq.info/get/bejne/h7dnnKeSzLfSgYE.html

@adrianTNT 3 жыл бұрын

If you stop moving and then move again, it can only detect motion again after around 4-5 seconds, is this normal ? With both jumper position. Continuous motion works OK (with the right jumper), but once you stop, it only detects motion again after 4-5 seconds.

@robojax 3 жыл бұрын

it should. I have shown how to adjust it. Watch it carefully. There is adjusting and position of object or something.

@christophervillaflores7423 2 жыл бұрын

Do we need to calibrate the sensor or just used this code directly?

@robojax 2 жыл бұрын

Do whatever bus shown in video. It will not work by default.

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?

have you watched the video? I just watched it to remind myself. you don't need any library. you need to adjust the sensitivity. watch carefully to so you learn.

My motion sensor has "L" and "H" printed on the board adjacent to three pads. However, it does not have jumper pins. Why doesn't my motion sensor have jumper pins? How can I select "repeat" or "no repeat" without the pins? My motion sensor is actually an HW-416-B Based upon your answers, I will decide whether to complain to the seller. Thanks.

@robojax 3 жыл бұрын

Hello, I just checked the image. for the module you use. When we we use jumper we connect the middle pint to L or H. so it is exactly the same as I've shown so connect the middle pint to L or the middle pint to H to get one of the result. there is not different. that is what I understood from the image.

@jeffbowyer4576 3 жыл бұрын

@@robojax Thank you for your kind response. My problem: there are no pins...just pads. To connect the middle pad to H, for example, I would need to put a little solder between the middle pad and the H pad. I don't understand why a manufacturer would make a motion sensor board with the L, middle, and H pads, but no jumper pins. Here's an image of a board like mine: arduino.en.alibaba.com/product/62255409775-813499796/HW_416B_Infrared_smart_device_Human_body_induction_ir_infrared_sensor_module_Imported_probe.html See--no jumper pins. Just L, middle, and H pads

@robojax 3 жыл бұрын

Yea I saw that , I did not say pin I said points so solder it to those points.

@robojax 3 жыл бұрын

Yes solder the points however you can either wire or just solder . I would solder wire through the hole , first clear the hole, pass wires though them and solder so they are secure. If you don’t use wire you might damage it with multiple soldering.

no calibration of the pir sensor in your code

@robojax Жыл бұрын

the calibration is done by rerating the potentiometer. watch the video and learn. code has nothing to do with it.

@bartoosterkerk682 Жыл бұрын

@@robojax thx for the reaction, thats they adjustment by the two potentiometers for time and distance, maybe calibration is not the right word what i mean is the startup time (calibration) of the whole sensor thats about 1 minute , this is essential part before starting to use it, read the technical data sheet of the sensor

@bartoosterkerk682 Жыл бұрын

@@robojax Power On Delay Like most PIR sensors, the HC-SR501 takes approximately 30 to 60 seconds after being turned on to go through the initialization sequence. At that time it learns the ambient infrared signature of the environment. Basically it’s calibrating itself to the environment to determine what constitutes motion. False triggers are likely to occur during this calibration time, so any triggers during this time should be ignored. Also make sure that there is not too much movement in front of the sensor when it is undergoing self-calibration as this may interfere with the calibration process.

@robojax Жыл бұрын

this module has variable resistor. if you set it in the wrong value/position, there is not code to help you. Just rotate it and set it.
