I was given a powerbeats. I found that the speaker and the buttons are heavily damaged. But somehow I was succeded to connect it with a nother speaker. Again I found that the control buttons are not working. I found two wires connected with the control board to motherboard(the main receiver chip) Golden-GND Yellow- Control Signal I am now confused if the control button is PWM type or resistor controlled. Resistor controlled means it can send different voltage for different signal. I am guessing this is a resistor type controller. Can anyone sketch a circuit diagram that can helps me to fix this problem and I can make buttons for this wireless earphone.
