What is the easiest way to output audio using arduino?
The audio output that I need will be a voice saying "turn left", "turn right", "The device is now turned on". "Error! Please press the reset switch." From these, I can estimate that each audio output will not exceed 5 seconds.
Additional info: My arduino uses ATMEGA 168 microcontroller.
Try connecting your speaker output on your computer to an analog output on the arduino, record the wavelengths, and then use one of the pwm outputs to produce those pulses and connect it to a speaker
