How to connect a real external speaker through a classic Jack connecter to the Board of Education?

So that I can send it FREQOUT instructions?

(instead of using the piezo-electric component)

I've not used this board before. But, I assume you could wire the existing piezo sounder to a simple amplifier and onto your speaker. An LM386 would be ideal.

I finally used a broken Jack wire : and it worked! – user3442 Mar 19 '11 at 20:54
