hey guys, i'm workin on a soil moisture sensing project and i want the output from the speakers..so can i use my normal speakers for this task?? anf if yes, kindly give me some idea regarding that.
Basically yes BUT.
- You need to put a 130R resistor in series with the speaker.
- It is also better if you also include a large electrolytic capacitor in series as well, something like a 470uF.
It will not be very loud. You should use the "tone" function to make it sound.
Better to take the 0-5V output from the Arduino, run it thru a cap and resistor voltage divider for a +/- 1V signal, into the input of powered speaker, like desktop computer speaker.
Will sound like this:
Thank u guys!!
i will work on this one, and if ny1 gets some new idea of using a normal laptop speaker, kindly suggest..as i'm very new to this stuff.
Thanks gain..
