I am trying to connect general speaker as an output to an Arduino Nano and play some tone.

My vision is:

  • will connect:
    • Arduino D8 (digital) output pin to left and right channel
    • GND to GND
  • in code, I will call tone(pin, frequency, duration) function to play tone - tone(8, 262, duration) (262 - C4 from example)

Vision schema

But in mentioned example, they use directly wired buzzer. My question is, if this will work as is on image, and if is it save (I will not damage both speaker and Arduino). I don't know, what voltage range is expected by speaker (on 3.5mm jack).

  • \$\begingroup\$ @JYelton ohh, I tryed to google, but I haven't found this - thank you. But there are 2 answers that contradict each other - one says large is better, one small is better. But the capacitator that is mentioned in first comment is probab needed (I found it in another forum in different case), but I dont understand where any how :( \$\endgroup\$
