An alternative joystick solution is the as5013 hall effect ic from ams which uses a tiny moving magnet to determine x y position.
Hall effect sensor joystick.
This a special version of arduino that can emulate as a usb hid joystick.
We have seen quite a few diy joystick designs that use hall effect sensors but akaki s controller designs youtube video embedded below really make the most of 3d printing to avoid the need.
With a class leading installed depth of 20mm it is available in 1 2 or 3 axis formats.
In order to compatible with arduino it should be powered by 5v and output 2 axis analog values in the range within 0 5v.
A third hall effect sensor is used to measure a throttle stick positioned on the side of the box.
To get enough conneciton points for 5vdc and gnd we need jumpers off the incoming usb connector.
Frequently a hall sensor is combined with threshold detection so that it acts as and is.
An arduino micro reads the sensors and converts the analog signal to usb.
Remove the board from the joystick so it can be modified.
Hall effect sensors are used for proximity sensing positioning speed detection and current sensing applications.
A hall effect sensor or simply hall sensor is a device to measure the magnitude of a magnetic field its output voltage is directly proportional to the magnetic field strength through it.
The 3000 series also delivers.
The optical joystick has only advantages over the inductive joystick hall effect joystick and potentiometer joystick.
Enjoy the videos and music you love upload original content and share it all with friends family and the world on youtube.
Hall effect joystick have many variant.
The as5013 is a complete solution that contains five sensors and a processing engine making integration with a host processor quite easy.
The 3000 series is the very latest generation in high precision contactless joysticks.
