Hi guys!
I'm new to Arduino and Microelectronics. Im bought an Seeed Grove Water Atomiz and an esp32 microcontroller and wanted to test it in a simple setup. First i setted it up like this:
I stupidly thought i had to connect the en pin on the board to the en pin on the grove module. The atomizer worked (humidified water) and stopped after one or two seconds.
I then connected it like below with the following code.
void setup() {
Serial.begin(9600);
pinMode(25, OUTPUT);
}
void loop() {
digitalWrite(25, HIGH);
Serial.println("Atomization ON");
delay(3000);
digitalWrite(25, LOW);
Serial.println(digitalRead(25));
delay(3000);
}
Now, it doesn't work and i don't know if i broke it or just made a mistake in the code. The Sertial.println works as expected. Is it possible that i destroyed the Grove module by attaching it to the EN pin? Is there a way i can test if it is functioning?
