I want to send pulses coming from a device to a smart phone through its audio jack.
I dont know where to start with.
What considerations should I look into?
I mean my idea was to count pulses so on off voltages appearing at the audio jack and read the freq. by an app.
How can I achieve the analog part? Does anyone have experience with this?
