const int motorPin2 = 3; // Digital output pin to control motor 2void setup() {
// Initialize motor pins as outputs
pinMode(motorPin1, OUTPUT);
pinMode(motorPin2, OUTPUT);
}void loop() {
// Read battery voltage
int batteryVoltage = analogRead(batteryVoltagePin);
float voltage = batteryVoltage 0.004882814; // Convert to voltage value (11.1V max)// Check if battery voltage is below 10.5V (recommended minimum for this battery)
if (voltage < 10.5) {
// Alert user to recharge battery
Serial.println("Low battery voltage! Please recharge.");
} else {
// Control motors based on battery voltage
if (voltage > 10.8) {
// Full speed
digitalWrite(motorPin1, HIGH);
digitalWrite(motorPin2, HIGH);
} else {
// Reduced speed
digitalWrite(motorPin1, LOW);
digitalWrite(motorPin2, LOW);
}
}delay(1000); // Wait 1 second before checking again
}

Example 2: Drone System with PX4 AutopilotIn this example, we'll use the 11.1 V 3000mah 3S 40C-80C Lithium Polymer Battery to power a drone system running PX4 Autopilot.
```c
// PX4 Autopilot code snippet (C++)#include <px4_platform_common/px4_platform_common.h>void DroneSystem::init() {
// Initialize drone system components
// ...// Initialize battery monitor
battery_monitor_.init();// Set battery voltage and capacity
battery_monitor_.set_voltage(11.1); // 11.1V nominal voltage
battery_monitor_.set_capacity(3000); // 3000mAh capacity
}void DroneSystem::update() {
// Update drone system components
// ...// Check battery voltage and state of charge
float battery_voltage = battery_monitor_.get_voltage();
float state_of_charge = battery_monitor_.get_state_of_charge();// Take action based on battery state (e.g., land or return to base)
if (state_of_charge < 20.0 || battery_voltage < 10.5) {
// Land or return to base
// ...
}
}
