Introduction

Hello geeks, we are back with another new post. We are sure that you know what a gimbal is. Well, it is used by professional cameramen for recording cinematic shots or high-quality videos. So in this article, we are going to make a gimbal stand with the help of an MPU 6050 gyroscope sensor and an Arduino UNO project. This gimbal stand can rotate in different directions and for this movement, we are using two servo motors. As we use a servo motor in this stand so the movement is not as smooth as the original one. There are some special types of BLDC motors used in an original stand. You can also read articles on IoT and Basic electronics. So without wasting any more time let us start.

Description

• The gyroscope sensor is used for detecting the change in position of an object or machine.
• In our project, it is used for balancing the top angle of the gimbal using servo motors.
• When we move or tilt the sensor, it will generate some values according to the angle of the movement.
• If you are not familiar with the interfacing of an MPU 6050 gyroscope sensor with Arduino then go through it first.
• The servo motor will move as we move the sensor left, right, front, back.
• You can use the pieces of cardboard for mounting the servo motor one over another.
• Make the connections properly as given in the circuit diagram and then upload the code.

Circuit Diagram for Gimbal Stand

• Take two servo motors and connect their positive supply wire with the 5 volts pin of the Arduino.
• Join their negative supply wire with the GND pin of the Arduino.
• Then connect the VCC and GND pins of the MPU 6050 gyroscope sensor with the 5 volts and GND pins of the Arduino.
• Attach the SCL and SDA pins of the sensor with the SCL (Analog-5) and SDA (Analog-4) pins of the Arduino.
• Join the INT pin of the sensor with the digital-2 pin of the Arduino.
• At last, connect the signal wire of the first servo motor with the digital-6 pin of the Arduino and the signal wire of the second servo motor with the digital-5 pin of the Arduino. Your circuit is complete now.

  val1= map(ax, -17000, 17000, 0, 179);

  pval1= val1;
}
val2= map(ay, -17000, 17000, 0, 179);
if (val2 != pval2){
  servo2.write(val2);
  pval2= val2;
}
delay(5);
}
