Code Examples

### Example 1: Basic Current Measurement using Arduino

In this example, we'll connect the WCS1500 to an Arduino board to measure the current flowing through a load.

Hardware Connections

WCS1500 VCC to Arduino 5V
 WCS1500 GND to Arduino GND
 WCS1500 OUT to Arduino A0 (Analog Input)

Software Code
```c++
const int sensorPin = A0; // WCS1500 OUT pin connected to Arduino A0
int sensorValue = 0; // variable to store sensor value
float current = 0; // variable to store calculated current

void setup() {
  Serial.begin(9600);
}

void loop() {
  sensorValue = analogRead(sensorPin); // read sensor value (0-1023)
  current = (sensorValue  5.0 / 1023.0)  100.0; // calculate current in Amps
  Serial.print("Current: ");
  Serial.print(current, 2);
  Serial.println(" A");
  delay(500);
}
```
### Example 2: Current Monitoring with Raspberry Pi (Python)

In this example, we'll use a Raspberry Pi to monitor the current flowing through a load and display the reading on a graphical user interface (GUI) using Python and the Tkinter library.

Hardware Connections

WCS1500 VCC to Raspberry Pi 5V
 WCS1500 GND to Raspberry Pi GND
 WCS1500 OUT to Raspberry Pi GPIO 17 (Analog Input)

Software Code
```python
import tkinter as tk
import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.IN) # WCS1500 OUT pin connected to GPIO 17

def read_current():
    sensor_value = GPIO.input(17)
    current = (sensor_value  5.0 / 1023.0)  100.0
    return current

def update_gui():
    current_value = read_current()
    current_label.config(text=f"Current: {current_value:.2f} A")
    root.after(500, update_gui)

root = tk.Tk()
root.title("Current Monitor")

current_label = tk.Label(root, text="Current: 0.00 A")
current_label.pack()

update_gui()
root.mainloop()
```
