hi, i m trying to operate the robot via atmega16 micro controller from the output of 8870 .. my 8870 is working fine ,deocoding all tones .. but the output voltage is quite low ,its about 1.72v .. and when i feed this voltage to atmega 16 then it detects it as low signal .. suggest some solution ,, as far as i know the output of 8870 must be arnd 5v ..i have rechecked my circuit and it seems fine ..
