Servo motor arduino circuit diagram4/10/2023 Additionally, the switch of the Joystick is programmed to control the LED connected to Pin 13 of Arduino UNO. Keeping these in reference, I have written the code such that, when the value from X-axis potentiometer falls below 300, the position of the X Servo is reduced by 5 from its current position and if the value from X-axis potentiometer becomes greater than 700, the position of the X Servo is increased by 5 from its current position.Ī similar code is implemented even for the Y-Axis potentiometer and the Y Servo. The idle values from the Joystick are 510 for X-Axis and 530 for Y-Axis in my case. Once the code is uploaded to Arduino, it starts reading the data from the joystick and the default position of both the servos is initialized to 90 (in the range of 0-180). The control wires (Yellow or Orange) of the Servo Motors are connected to Digital I/O Pins 10 and 11. myservo.attach(9) To move the servo arm, you use the servo.write () function like so: 1. You then need to attach the Servo object to a pin: 1. +5V and GND to +5V and GND of Arduino, VRx and VRy to A0 and A1 (Analog Inputs 0 and 1) and the SW pin to Digital Pin 2.Ĭoming to the servo motors, their +V (Red) and GND (Brown) wires are connected to +5V and GND (preferably to another 5V Supply with common GND with Arduino). Servo myservo According to the creators of the Servo library, you can create up to 12 servo objects for the UNO and most other boards and up to 48 for the Arduino Mega. The connections with respect to the Joystick Module are the same i.e. View raw Arduino_Joystick_Servo.ino hosted with ❤ by GitHub The following circuit diagram shows the necessary connections for controlling two Servo Motors using a Joystick and Arduino.ĪttachInterrupt( digitalPinToInterrupt(switchPin), switchISR, CHANGE) the X and Y movements of the Joystick, you can control different devices like a Servo Motor, for example and with the Digital Input (the Switch), you can control an LED i.e. Which means, you get two different sources of Analog Inputs and one Digital Input. ![]() In case of a Joystick Module, you get two potentiometers and a switch. You have to collect the data from the sensor and use to appropriately. There is no use in just interfacing a sensor with Arduino. Related post: ARDUINO SERVO MOTOR How to Control Servo Motor with Arduino and Joystick? The next step in the Arduino Joystick Interface is to collect the values from the Joystick and use them to control a device, like an LED, motor or a servo. Since the input is Analog and we are converting it to Digital values, the output of the Joystick on both X-axis and Y-axis will be in the range of 0-1023. In that you can see the current values from both the potentiometers as well as the switch being updated on a regular basis (based on the delay). The switch pin on the other hand, is connected to Digital I/O Pin 2, with internal pull-up (implemented through code).Ĭoming to the working of the circuit, once the connections are made and the code is uploaded to Arduino, open the serial monitor. Servo Motor Controller Circuit Schematic. Since the VRx and VRy pins are the wiper pins of the Potentiometers, they must be connected to the Analog Input pins of the Arduino UNO (as they give us analog voltages). If the pulse is longer than 1.5ms, the shaft turns closer to 180 degrees. I think the design of the circuit is very clear. ![]() Please see the video below for more details.View raw Arduino_Joystick_Interface.ino hosted with ❤ by GitHub You can see that the servo motor is rotating as per the program. Wire the circuit properly as per the circuit diagram and upload the program.
