Audio Sensor circuit JP1 can set the output as analog or digital “sPlan” chart prepared by the “sprint layout” has been prepared by the PCB file. Robots can be useful for different projects or a circuit
The submission represent experimental module double sonic sensor on the basis of two audio amplifiers and double LM386 comparator LM393
The scheme is quite simple sound sensor and is a standard inclusion of elements. Audio Amplifiers LM393
R5 resistor construction allows it to adjust the threshold comparator operation – sensitivity. Thus at the exit scheme, we get two logical signal – from right and left of microphones. Also, there is an opportunity to process an analog signal directly from the amplifier through the ADC. J1. Options outgoing signals switched through two jumpers in the shoe J1.
