### Example 1: Arduino-based Drone Control using A2212 1400KV BLDC Motor and Simonk 30A ESC
This example demonstrates how to control the A2212 1400KV BLDC motor using an Arduino board and the Simonk 30A ESC.
```c
#include <Servo.h>
#define MOTOR_PIN 9 // Pin 9 for motor control
#define ESC_PIN 10 // Pin 10 for ESC control
#define PWM_FREQ 50 // PWM frequency in Hz
Servo motor; // Create a servo object for motor control
void setup() {
motor.attach(MOTOR_PIN); // Attach motor to Pin 9
pinMode(ESC_PIN, OUTPUT); // Set Pin 10 as output for ESC control
}
void loop() {
int throttle = 50; // Set throttle value (0-100)
int pwmValue = map(throttle, 0, 100, 1000, 2000); // Convert throttle to PWM value
motor.writeMicroseconds(pwmValue); // Send PWM signal to motor
delay(20); // Wait 20ms before sending next signal
}
```
In this example, the Arduino board sends a PWM signal to the Simonk 30A ESC, which controls the A2212 1400KV BLDC motor's speed. The `map()` function is used to convert the throttle value (0-100) to a PWM value (1000-2000).
### Example 2: Raspberry Pi-based Drone Control using Python
This example demonstrates how to control the A2212 1400KV BLDC motor using a Raspberry Pi and the Simonk 30A ESC with Python.
```python
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM) # Set GPIO mode to BCM
MOTOR_PIN = 17 # Pin 17 for motor control
ESC_PIN = 23 # Pin 23 for ESC control
PWM_FREQ = 50 # PWM frequency in Hz
GPIO.setup(MOTOR_PIN, GPIO.OUT) # Set Pin 17 as output for motor control
GPIO.setup(ESC_PIN, GPIO.OUT) # Set Pin 23 as output for ESC control
pwm = GPIO.PWM(MOTOR_PIN, PWM_FREQ) # Create a PWM object
while True:
throttle = 50 # Set throttle value (0-100)
pwm_value = int((throttle / 100) 2000) + 1000 # Calculate PWM value
pwm.ChangeDutyCycle(pwm_value) # Send PWM signal to motor
time.sleep(0.02) # Wait 20ms before sending next signal
```
In this example, the Raspberry Pi's GPIO library is used to create a PWM signal on Pin 17, which is connected to the Simonk 30A ESC. The ESC then controls the A2212 1400KV BLDC motor's speed based on the PWM signal. The `ChangeDutyCycle()` function is used to set the PWM duty cycle.
Note: These code examples are for demonstration purposes only and may require modifications to work with your specific drone setup and configuration. Additionally, ensure that you follow proper safety precautions when working with electrical components and flying drones.
