DIY - Universal RC Joystick: controls

Based on the solution of designing multi-functional remote controller and being aware of the needs we started building the joystick. It will have 4 push buttons, 2 switch buttons, 2 potentiometers and two analog modules. And, additional 2 push buttons integrated on the analog joystick module.

Below you will find links to previous project posts.

Components

Prerequisites

Understanding how each of the control elements work separately:

• How to use an analog module with Arduino

• How to use potentiometer with Arduino

• Using push buttons with Arduino

• Using switch buttons with Arduino

Controls

Joystick controls are mounted on the frontal structure. Their positions were chosen to make holding comfortable and within the range of the fingers.

Joystick forepart has the openings for both analog joystick modules. However, the part itself is located on the backside. Take into consideration, as we mentioned before, that each analog module has integrated push button.

Wiring

That's it, our cover is ready so we can continue with the wiring. To make it easier we have soldered one side of dupont cables to the control element leaving the other side with the connector. That way we can directly plug it to a breadboard (using pins) or a pinned module.

Once finished the forepart we proceed with the backside.

Conclusion

Our remote controller end up having 8 buttons, 2 potentiometers and 2 biaxial joysticks. It should be more than enough to manage another non-complex device. In the following posts, we will share details about mounting process and the code used to run AirControl.
