Here are a few code examples that demonstrate how to use the Witty Fox 11.1V 2200mAh Li-Ion Battery in various contexts:
### Example 1: Arduino Battery Monitoring
In this example, we'll use 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) 2200;
Serial.print("Battery Voltage: ");
Serial.print(voltage);
Serial.println("V");
Serial.print("Battery Capacity: ");
Serial.print(capacity);
Serial.println("mAh");
delay(1000);
}
```
### Example 2: ESP32 Low Power Application
In this example, we'll use an ESP32 board to demonstrate a low-power application that consumes minimal power when not in use.
const int batteryPin = 32; // GPIO pin for battery monitoring
WiFiClient client;
void setup() {
Serial.begin(115200);
WiFi.mode(WIFI_OFF);
}
void loop() {
int sensorValue = analogRead(batteryPin);
float voltage = sensorValue (11.1 / 4095.0);
if (voltage > 10.5) {
// Perform tasks that require Wi-Fi connection
WiFi.mode(WIFI_STA);
client.setServer("example.com", 80);
client.println("GET / HTTP/1.1");
client.println("Host: example.com");
client.println("Connection: close");
client.println();
} else {
// Enter low-power mode to conserve battery life
WiFi.mode(WIFI_OFF);
esp_sleep_enable_timer_wakeup(30 60 1000000); // Wake up every 30 minutes
esp_light_sleep_start();
}
delay(1000);
}
```
### Example 3: Raspberry Pi Power Management
In this example, we'll use a Raspberry Pi to demonstrate power management techniques using the Witty Fox 11.1V 2200mAh Li-Ion Battery.
```python
import time
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.IN, pull_up_down=GPIO.PUD_UP) # GPIO 17 for battery monitoring
while True:
voltage = GPIO.input(17)
if voltage > 10.5:
# Perform tasks that require high power
print("High power mode")
else:
# Enter low-power mode to conserve battery life
print("Low power mode")
time.sleep(30 60) # Sleep for 30 minutes
```
These examples demonstrate how to use the Witty Fox 11.1V 2200mAh Li-Ion Battery in various IoT applications. By properly connecting the battery and implementing power management techniques, you can ensure reliable and efficient operation of your devices.
