This Arduino Joystick tutorial will show you how to connect an 2 axis joystick to using any two Arduino analogue inputs. The joystick has two potentiometers one for vertical movement and one for horizontal movement. All that happens is that you put 5V at one end of the potentiometer and 0V at the other end of the potentiometer, and the wiper adopts a value in between these voltages.
Then all you do is read the analogue values using an Arduino using the Arduino adc. This picture shows the physical structure of the Arduino joystick - two potentiometers to top and right with the control stick in the middle. The following sketch does not require a library and just reads and displays the values from analogue input A0 and A1. It also displays the button push output. The values show that the joystick returns to centre values are the same i. Download it from : Here.

I promise to use it only to send you MicroZine. Note: Of course whether VRx is horizontal and VRy is vertical depends on the orientation of the module. That won't really matter so change it in software as needed.
The button input pin is connected to ground when pushed, so you need a pullup on that connection - that is easily done using the internal pullup in an Arduino see the sketch below for how to do that.

Especially for robotics. As hardware hackers most of us have always loved these sorts of things. Except the new guys to this might find it hard to grasp the concept during coding and such. That is what this instructable is for. Knowledge is a tool all should have, so in this I will try to give others some additions to their tools of knowledge. Let's begin! Did you use this instructable in your classroom?

At first I tried 5 volts, but the results weren't the best so I changed it to 3. After that the results were perfectly fine. If you're not afraid to mod some stuff control your room fan with a joystick I am not to be held accountable for the stupid acts you may do. Check your connections! I don't know how many times something didn't work and it turns out it wasn't connected right.
Check you code! Code is very picky about stuff. Make sure it does exactly what you want. Simple code that works is better than complicated code that doesn't! By now you should know the basics of using a joystick with your Arduino because you can just check for certain values of the joystick's potentiometers. I am planning on more projects I've got some Xbees i want to use so please give some suggestions. Reply 4 years ago.Using an Analog Joystick with an Arduino —.
I know this because I checked my serial monitor and clicked baud rate option. So where ever you seeremove it and write instead. Never mind I wired my cables wrong, now the problem is fixed. So if any you have a solution to this please let me know, thanks again. All i can see is tutorial about this but never ever mention how to connect to other device maybe we are just nub bro. Hi If anyone could help me it would be greatly appreciated.
So when ever I run Serial Monitor my codes end up differently, this is how they look:. I would just like to have my joystick read inputs so that I can use this for a future game-controller project.
Once again If anyone could please help me it would be greatly appreciated. It always gives 0, either I press the joystick button, or no. Have you any idea about it? The joystick is not working correctly for me. How to connect and use Analog Joystick with Arduino.
In this tutorial we will learn how to use an analog joystick module. When the joystick is in the resting position or middle, it should return a value of about The range of values go from 0 to By brainy-bits T January 12th, Tutorials.Legal memorandum sample pdf

Hennerzockt January 23, at am - Reply.The first thing that comes in our mind listening to the word Joystick is the game controller.
Apart from gaming, it has many other applications in DIY electronics. This joystick is nothing but a combination of two potentiometers for X and Y plane respectively.
It reads the voltage through the potentiometer and gives analog value to the Arduino, and the analog value changes as we move the joystick shaft which is simply the potentiometer pointer. We have placed 4 LEDs in such a way that it represents the direction of the joystick shaft movement. This joystick also has a push button which can be used for various other purposes or can be left idle.
This Joystick module typically provides Analog Outputs and the output voltages provided by this module keep changing according to the direction in which we move it. And we can get the direction of movement by interpreting these voltage changes using some microcontroller. This joystick module has two axes as you can see. They are X-axis and Y-axis. The midpoints of these pots are driven out as Rx and Ry. So Rx and Ry are variable points to these pots.
When the Joystick is in standby, Rx and Ry act as a voltage divider. When the joystick is moved along the horizontal axis, the voltage at Rx pin changes. Similarly, when it is moved along the vertical axis, the voltage at Ry pin changes. When the stick is moved, the voltage on each pin goes high or low depending on direction. In below code, we have defined X and Y axis of the Joystick module for analog pin A0 and A1 respectively.
Now, in the below code, we are initializing PIN 2 of Arduino for the Switch push button of the Joystick module and the value of buttonstate and buttonstate1 will be 0 at the start.
In the below code, we are setting up the baud rate to and defined Pin 7 as an output pin and button pin as an input Pin. Initially, the button pin will remain high until the Switch will press.The Analog Joystick is similar to two potentiometers connected together, one for the vertical movement Y-axis and other for the horizontal movement X-axis.
The joystick also comes with a Select switch. It can be very handy for retro gaming, robot control or RC cars. So let's understand how it works! Hence the values on each analog channel can vary from 0 to The home position for the stick is at x,y, If the stick is moved on X axis from one end to the other, the X values will change from 0 to and similar thing happens when moved along the Y axis.
On the same lines you can read position of the stick anywhere in upper half hemisphere from combination of these values.
It is usually not enough to read the analog values, you might want to map it to a display or any other interface.
So let's map these these values to a 8x8 led matrix. So that we can move the pixel with the joystick. You can easily change this to map to a graphic or a OLED display.Opel zafira life camper
So as you see in the code above, the map function can be used to map the ranges as you wish. Also notice that the Y axis map is inverted! So much to learn with a simple interface! Do checkout the retro ping-pong game built with the same setup.

MeArm robot - joystick servo recorder - test board Download. Testing board with only two servos connected. See schematic diagram to connect 4 servo motors.I will discuss about the Analog Joystick Module, what a typical Joystick module consists of i.
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. An 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 knob or a protrusion is used to change the position of the potentiometers. The following image shows the internal components of a typical Analog Joystick. The following image shows the internal connections in a Joystick Module. A typical Joystick Module consists of 5 Pin on its board. They are:.
The following image shows the pin diagram of the Joystick Module I am using. The orientation of the pins may vary depending on the manufacture but the pins will be the same.
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. Since, the joystick is essentially a combination of two potentiometers and a Switch, of courseyou can easily guess how to interface it with Arduino as you might have already connected a potentiometer with Arduino. I think the design of the circuit is very clear.
Using a Joystick With Your Arduino
Coming to the working of the circuit, once the connections are made and the code is uploaded to Arduino, open the serial monitor. 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.
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 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. There is no use in just interfacing a sensor with Arduino. You have to collect the data from the sensor and use to appropriately. In case of a Joystick Module, you get two potentiometers and a switch.
Which means, you get two different sources of Analog Inputs and one Digital Input. Using the Analog Inputs i. The following circuit diagram shows the necessary connections for controlling two Servo Motors using a Joystick and Arduino.
The connections with respect to the Joystick Module are the same i. 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 Keeping these in reference, I have written the code such that, when the value from X-axis potentiometer falls belowthe position of the X Servo is reduced by 5 from its current position and if the value from X-axis potentiometer becomes greater thanthe position of the X Servo is increased by 5 from its current position.
