Hi, I build the Mems Microphone ICS40180 but I have some issues. I tested continuity with all smd components and they are ok. I measured voltage on the A0 pin is around 1.65-1.7v but after uploaded the sketch:
/***************************
Simple Example Sketch for the SparkFun MEMS Microphone Breakout Board
**************************/
// Connect the MEMS AUD output to the Arduino A0 pin
int mic = A0;
// Variable to hold analog values from mic
int micOut;
void setup() {
Serial.begin(9600);
}
void loop() {
// read the input on analog pin 0:
micOut = analogRead(mic);
// print out the value you read:
Serial.println(micOut);
}
on the serial monitor I have values around 350 and If I snap, clap, or speak doens’t change anything. I measured with oscilloscope and seems like doesnt’ capture any signal… I attached some images here on the post. Any help to troubleshooting? Thanks in advance!
