With the Servo Controller, you can wirelessly control multiple servos using the BlueBot app. Whether you’re working on a robotics project or simply exploring servo motors, this servo controller allows you to adjust the angles of multiple servos from 0 to 180 degrees, giving you full control over your project. The servo controller provides a smooth and efficient way to control your servos, even from a distance.
How the Servo Controller Works
The servo controller uses Bluetooth to communicate with your servo motors. By connecting the servo motors to the appropriate pins on your Arduino board, you can control them remotely through the BlueBot app. The servo controller works by sending commands via Bluetooth to adjust the positions of the servo motors gradually. This enables precise control of your servos.
Features of the Servo Controller
- Wireless Control: With the servo controller, you can easily control the servo motors without the need for direct wiring, using Bluetooth for communication.
- Adjustable Angles: You can set the angle of your servos anywhere from 0 to 180 degrees, providing versatility for different applications.
- Smooth Movement: The servo controller allows for smooth and gradual servo movements, thanks to the speed control feature.
- Multiple Servo Control: With the servo controller, you can manage multiple servos at once, making it ideal for complex projects like robotics.
How to Use the Servo Controller
To use the servo controller, you need to follow these simple steps:
- Connect Servos: Connect the servo motors to your Arduino.
- Upload Code: Upload the servo control code to your Arduino using the Arduino IDE.
- Connect Bluetooth: Pair your Bluetooth module with the BlueBot app.
- Control Servos: Use the app to control the servo positions remotely.
Servo Controller Code
Here’s the full code to control two servos wirelessly using Bluetooth:
#include <SoftwareSerial.h>
#include <Servo.h>
// Declare Servo objects for two servos
Servo servo01;
Servo servo02;
// Initialize Bluetooth serial communication
SoftwareSerial Bluetooth(2, 3); // Arduino (RX, TX) - HC-05 Bluetooth (TX, RX)
// Variables for servo 1
int servo1Pos = 90, servo1PrevPos = 90; // Current and previous positions
int servo1SpeedDelay = 20;
// Variables for servo 2
int servo2Pos = 90, servo2PrevPos = 90; // Current and previous positions
int servo2SpeedDelay = 20;
String dataIn = ""; // To store incoming Bluetooth data
void setup() {
servo01.attach(10); // Attach servo 1 to pin 5
servo02.attach(6); // Attach servo 2 to pin 6
Bluetooth.begin(9600); // Initialize Bluetooth
Bluetooth.setTimeout(50); // Increase timeout for stable connection
// Set initial positions for both servos
servo01.write(servo1PrevPos);
servo02.write(servo2PrevPos);
delay(20);
Serial.begin(9600); // For debugging
}
void moveServoGradually(Servo &servo, int &prevPos, int targetPos, int speedDelay) {
if (prevPos > targetPos) {
for (int j = prevPos; j >= targetPos; j--) {
servo.write(j);
delay(speedDelay / 2);
}
} else if (prevPos < targetPos) {
for (int j = prevPos; j <= targetPos; j++) {
servo.write(j);
delay(speedDelay / 2);
}
}
prevPos = targetPos; // Update previous position
}
void loop() {
if (Bluetooth.available() > 0) {
dataIn = Bluetooth.readStringUntil('\n'); // Read data until newline
Serial.println("Data received: " + dataIn); // Debugging
// Handle commands for Servo 1
if (dataIn.startsWith("J1")) {
String dataInS = dataIn.substring(2);
servo1Pos = dataInS.toInt();
if (servo1Pos < 0) servo1Pos = 0;
if (servo1Pos > 180) servo1Pos = 180;
moveServoGradually(servo01, servo1PrevPos, servo1Pos, servo1SpeedDelay);
}
// Handle commands for Servo 2
if (dataIn.startsWith("K1")) {
String dataInS = dataIn.substring(2);
servo2Pos = dataInS.toInt();
if (servo2Pos < 0) servo2Pos = 0;
if (servo2Pos > 180) servo2Pos = 180;
moveServoGradually(servo02, servo2PrevPos, servo2Pos, servo2SpeedDelay);
}
}
}
Understanding the Code
- Library Setup:
The Servo library is used to control the servo motors, and the SoftwareSerial library is used for communication with the Bluetooth module. - Pin Setup:
The servo motors are connected to pins 10 and 6 of the Arduino. The Bluetooth module is connected to pins 2 and 3. - Bluetooth Communication:
Bluetooth communication begins at a baud rate of 9600. The Bluetooth module receives commands such as “J1” or “K1” followed by an integer representing the angle of the servo (0 to 180 degrees). - Servo Movement:
The functionmoveServoGradually()allows the servos to move smoothly by gradually increasing or decreasing their position. The movement speed is adjustable using theservoSpeedDelayvariable. - Control Logic:
Based on the Bluetooth command received, the corresponding servo moves to the desired position. For example, a command “J1” will control servo 1, and “K1” will control servo 2.
How to Use the Servo Controller
- Download the BlueBot App:
Install the BlueBot Controller app on your Android device. Make sure your Bluetooth is enabled. - Pair the Bluetooth Module:
Pair your HC-05 Bluetooth module with your Android phone via the Bluetooth settings. - Send Commands:
In the app, use the slider to adjust the angles of the servo motors. The app sends commands like “J1” for servo 1 and “K1” for servo 2, followed by the desired angle. - Enjoy Wireless Control:
Watch as the servo motors respond to the angle changes you make through the app, with smooth and precise adjustments.
