Speaker port on PI board

[mvillion]

I was digging through the documentation and noticed the audio port was highlighted, indicating that the port was important.

Is the audio port used in the project and if so, what is required to make it work?
If it can be used to provide user feedback, then I am thinking I want to go there.

Yes, text-to-speech has been part of FBOS for many years.

eSpeak text-to-speech: 1.48.03  04.Mar.14  Data at: /usr/share/espeak-data

It’s ready to use in the SEND MESSAGE Sequence block using the SPEAK checkbox.

I have assembled a little audio amplifier to make this work.

My Farmbot is speaking (Audio Voice out)

I have come up with a little project the add an audio amplifier to the Raspberry PI which allows Farmbot to provide audio feedback at the head. Great for local confirmation feedback of buttons or reporting progress or errors. You 'talk though LUA command like this. send_message("info", "hello Human. I am Farmbot. Surrender now become part of my slave army. ", {"toast", "espeak"}) It runs on 5 Volts, is tiny and fits nicely into the control box. Would anyone be interested in a kit?

It works great!

Finally. User feedback beyond LED 3 and LED 4
