instead of the relay you can just use a voltage divider as a level shifter to get the voltage down to the proper voltage for the arduino digital input pin 5 or 3.3 volt depending in which arduino you use.

A optocoupler would also work

this input_pullup function was new to me, verry usefull , thanks a lot

@DuctTapeMechanic 3 жыл бұрын

Yes its a great function. Before I knew about it, I used to use actual pullup resistors to achieve this. Thanks for watching!

Very well explained. Thanks. I just bought an arduino uno and a proximity sensor. I would like the buzzer however to only go off when something passed by the sensor every say third time. Basically have the arduino count the amount of times the sensor is triggered and buzz when it reaches the set amount like with every third item. Is that possible and how would you do that? Would you do a video on that for us?

Npn sensor will pull ground when activate. Direct connet pull up input arduino.

thank you I have a small question what should i do to make a counter to count the number of metals ?

That's really cool! What do we do if we want the sensor to beep before the object gets too close, do we just get a stronger sensor or can this be controlled with Arduino code?

@DuctTapeMechanic 4 жыл бұрын

Thanks. This sensor has a screw on the top which allows for some variation of the sensitivity but a better sensor would be the way to go.

Hi, I don't understand what you meant by connecting to the anode if you want the relay to do the opposite. Anode of what? . Does a coil have an anode?

Be careful with cheap sensors unless the application isn't critical. They usually have EMC and temperature drift problems.

you can simplify using BC547

Yes that will probably work. I recommend us pc817 for an alternative way to do this

Is there a way to control the sensitivity of the proximity sensor using arduino code? if not what should i find to be able to do it?

You can adjust the sensitivity on the sensor itself using the set screw

Its called a 12v dpdt relay. Thank you for watching. www.amazon.com/Electromagnetic-Socket-Mechanical-Indicator-LY2N-J/dp/B07SYYP41M/ref=mp_s_a_1_7?dchild=1&keywords=DPDT%2BRelay&qid=1604236771&sr=8-7&th=1&psc=1

Thank you for sharing your knowledge. My question is whether it is possible for a sensor to reverse the current in a circuit any time it detects a target. And if so how can it be done?

@DuctTapeMechanic 2 жыл бұрын

Just hook up the dpdt relay with a cross pattern this will reverse polarity when something is detected. You don't even need an Arduino. Just go from sensor to dpdt relay to dc motor (I presume)

What is the relay for?

@DuctTapeMechanic Жыл бұрын

Just a rudimentary way to interface the 12 volt sensor with the arduino a PC817 optocoupler would be a more elegant choice

@mftest100 2 жыл бұрын

Hey, great video - I've missed this, (I am a total beginner) what is the purpose of building in the relay ? Hope you can enlighten me :-)

@DuctTapeMechanic 2 жыл бұрын

Good question. The relay acts as a switch. Basically when the sensor is triggered (something is detected) it "turns on" the relay which in turn grounds out the arduino pin. And the pin going to ground can be coded for (i.e. sensed by the arduino). The relay helps integrate the sensor with the arduino while keeping them electrically isolated, a more elegant (more proper) way to do this would be to use a PC817 optcoupler instead of a relay (but this does work). I was kind of working with what I had at the moment.

In a nutshell, it serves as a voltage isolation mechanism. There are probably a lot of better ways to do it. Just what I thought of at the time.
