As mentioned in my previous post, I've been working on things related to audio output. Tonight I breadboarded a simple amplifier using an LM386. I decided to run a smoke test, and connected it to the 5V output on the LM3S1968 board with the input open.
When I turned it on, I got light buzzing. I decided to see what happened when I moved the 10k pot... suddenly, my speaker was spewing forth a synthesized voice. I was shocked and moved my hand... the sound stopped. Touching the pot again caused the voice to return.
I soon realized that I was picking up some local AM radio station (I could also hear other stations in the background), but it is quite the conicidence for that station to be running an interview with Roger Ebert, who uses a synthesized voice??!
I momentarily wondered if I had gone mad. :-)
