I think the design of the circuit is very clear. The following image shows a simple connection between Arduino UNO and the Joystick Module.
#SERVO MOTOR ARDUINO CODE KNOB HOW TO#
Since, the joystick is essentially a combination of two potentiometers (and a Switch, of course), you can easily guess how to interface it with Arduino as you might have already connected a potentiometer with Arduino. how to interface a Joystick with Arduino? Now that you are familiar with the components and pins of a typical Joystick Module, let me take you through the Arduino Joystick Interface i.e.
The orientation of the pins may vary depending on the manufacture but the pins will be the same.
The following image shows the pin diagram of the Joystick Module I am using. The VRx and VRy are the Wiper terminals of the two potentiometers.įinally, SW is one end of a switch, where its other terminal is connected to GND (on the board of the Joystick). Here, +5V and GND pins must be connected to, well +5V and GND of a power supply (you can connect them to respective pins on Arduino). Pins of a JoystickĪ typical Joystick Module consists of 5 Pin on its board. As mentioned earlier, it consists of two 10KΩ Potentiometers, a push button (switch) and connectors (Pins). The following image shows the internal connections in a Joystick Module. There are two Potentiometers of 10KΩ each and additionally there is a switch which can be activated by pushing the knob down. The following image shows the internal components of a typical Analog Joystick. A knob or a protrusion is used to change the position of the potentiometers. NOTE: For the rest of the project discussion, only the term “Joystick” is used.Ī typical Joystick module is shown in the following image.Īn Analog Joystick usually consists of Potentiometers (two for each axis) and based on the position of these potentiometers, input is given (to a microcontroller, for example). A Joystick (sometimes also called as Thumb stick) is an input device and the Analog Stick is a type of Joystick which provides a 2-Dimensional Input. You might have come across Joystick or Analog Stick as a Game Controller Device. How to Control Servo Motor with Arduino and Joystick?.
