### Example 1: Arduino-based Battery Monitoring System
This example demonstrates how to use the 11.1V 8000mAh Orange Lithium Polymer Battery with an Arduino board to monitor the battery voltage and capacity.
```c++
const int batteryPin = A0; // Analog input pin for battery voltage measurement
void setup() {
Serial.begin(9600);
}
void loop() {
int sensorValue = analogRead(batteryPin);
float voltage = sensorValue (11.1 / 1023.0);
float capacity = (voltage / 11.1) 100;
Serial.print("Battery Voltage: ");
Serial.print(voltage);
Serial.println(" V");
Serial.print("Battery Capacity: ");
Serial.print(capacity);
Serial.println(" %");
delay(1000);
}
```
### Example 2: Raspberry Pi-based Drone Power System
This example demonstrates how to use the 11.1V 8000mAh Orange Lithium Polymer Battery to power a Raspberry Pi-based drone system.
```python
import RPi.GPIO as GPIO
import time
# Initialize the GPIO pins for the battery monitoring
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.IN, pull_up_down=GPIO.PUD_UP) # Battery voltage monitoring pin
while True:
# Read the battery voltage
voltage = GPIO.input(17)
if voltage:
print("Battery voltage is above 10.5V")
else:
print("Battery voltage is below 10.5V")
time.sleep(1)
```
Note: In this example, the Raspberry Pi is powered directly from the battery, and the GPIO pin 17 is used to monitor the battery voltage. The voltage threshold for the low-battery warning is set to 10.5V.
### Example 3: ESP32-based IoT Node Power Supply
This example demonstrates how to use the 11.1V 8000mAh Orange Lithium Polymer Battery to power an ESP32-based IoT node.
// Initialize the ESP32 ADC pin for battery voltage measurement
const int adcPin = 32;
void setup() {
Serial.begin(115200);
WiFi.begin("your_wifi_ssid", "your_wifi_password");
}
void loop() {
int adcValue = analogRead(adcPin);
float voltage = (adcValue 11.1) / 4095.0;
Serial.print("Battery Voltage: ");
Serial.print(voltage);
Serial.println(" V");
// Send the battery voltage data to the cloud or a remote server
// ...
delay(1000);
}
```
Note: In this example, the ESP32 is powered directly from the battery, and the ADC pin 32 is used to measure the battery voltage.
