To read a current sensor with an Arduino, you will need the following:
Here are the steps to read the current sensor with an Arduino:
void setup() {
Serial.begin(9600); // Initialize serial communication at 9600 bits per second
}
void loop() {
int sensorValue = analogRead(A0); // Read the analog input from the current sensor
float current = (sensorValue / 1023.0) * 5.0; // Convert the analog value to current (assuming a 5V input)
Serial.println(current); // Print the current value to the serial monitor
delay(1000); // Wait for 1 second before reading the sensor again
}
Note: The code assumes that the current sensor outputs a voltage proportional to the current being measured. You may need to modify the code if your current sensor works differently. Additionally, be careful when working with high currents and voltages, as they can be dangerous.
