Hi all
Completely new to the ESP32. I have had some experience with arduino. I am trying to find some example code showing how to use the SW-420 vibration sensor with the ESP32. I find a lot of arduino examples but none for the ESP32. My goal is to transmit via ethernet when movement starts and stops.
But I think getting the sensor working is the first step. Can someone point me to some example code for this.
Thank you
After more research it seems that the ESP32 is supposed to be able to run arduino sketches. I have successfully installed and ran sample programs for the ESP32 but have not been able to run arduino sketches. I have this sketch to run the vibration sensor for the arduino
int Vibration_signal = B10;
int Sensor_State = 1;
void setup() {
pinMode(Vibration_signal,INPUT);
Serial.begin(9600);
}
void loop() {
Serial.print("Vibration Status: ");
Sensor_State = digitalRead(Vibration_signal);
if (Sensor_State ==1){
Serial.println("Machine Running");
}
else {
Serial.println("Machine Stopped");
}
delay(50);
}
But When I try to compile and run the code I receive the following error. Any suggestions as to what to do to fix it would be appreciated.

Hi Timk5000,
I tried this with a new unit just received, Seems to work OK.

Sorry for the delay in reply. It seems that my Arduino IDE may have been to old or damaged. After refreshing the install of the Arduino IDE was able to compile and load the code you provide. Thanks for your help.
Hi @PJ_Glasso ,
I see a power profile kit in the photo, is it worth it to measure the total current measurement of modules/PCB?
I have designed a PCB with has a xiao esp32s3 and some sensors connected, I want to calculate total power consumption so that I can use a suitable battery according to the power consumption.
In a word YES, $99 will tell you if your on the right track for battery and power savings or BLOTED, It helped me find some code that was leaving allot of wasted juice. (BLE)
It’s also a cheep way to get 9 0r 10 channels for logic analyzing as a bonus so to speak.
None of the power stuff of Seeed studios is to be trusted as FACT so VERIFY, VERIFY, and RE-Verify when they update board files & spec’s . IMO YMMV
