I am playing around with some linear actuators (Glideforce) and Pololu USB Motor Controllers with feedback and an Arduino Mega 2560. Currently I am using a little Sunfounder Joystick PS2 module. The joystick PS2 module has two lines of analog output (X, Y) and one of digital output (Z). The cross rocker is a bidirectional 10k resistor. It's ok for playing around, but does anyone have any experience or recommendations for a bigger joystick that I can just drop in and not have to rewrite code (for now, its a very simple application)? Preferably one that is panel mounted and isn't hundreds of dollars? I would like one that is a bit more durable for a class that I will be teaching....TIA!
From what I can find with the link you posted to the Sunfounder Joystick PS2 module it appears to have two pots internal and a switch. Most any analog joystick should work. Not all have the switch and it may not be configured the same. Look for some bigger ones and see what they tell you.
Any Nintendo will easily work. The following code was used for a servo powered lock and required the user to successfully input the Konami code of NES fame. I also adapted the code to work the internals on a mock up of the TARDIS interior I did for Halloween one year by assigning different buttons and directions to different outputs: lights, sounds etc.
/*
No need to add LED lighting code explicitly, it's all already here!
Adding the LEDs to pins 5, 6, and 8 (A, B and start) allows other free effects
too using the NES Advantage TURBO and SLOW buttons and dials
Adapted from Adafruit "Classy Solution" by Hallowed31 to use Nintendo controller
instances instead of led instances

Sounds good, thanks!
Outstanding, thanks, this helps!
