Section 1 - Finding a Speaker
After experimenting with several Arduino projects, I was ready to try something with sound.
I searched eBay for a suitable speaker. I researched piezo devices and was pretty much
confused by all the choices. One vendor included a link to a manufacturer's product line
which listed dozens of miniature speakers and their recommended uses. One item caught my
eye. It was a tiny speaker used in telephone handsets.
I realized right away that I had a junk box with several old telephones that were long ago replaced by newer cord less models. I decided to hack my way into one of the handsets to see what I might find inside. |

I removed a screw and forced my way into the case. Good news! Hiding under a metal strap was a speaker
with two wires attached.
I removed a few more parts, clipped the wires and the treasure was free to come out. I had my speaker and it didn't cost me a thing! I could hardly wait to give it a try. Come on, boy. It's time to teach Arduino to 'speak.' |
