Simple joystick speed control

Hello! and Thank You! in advance for any advice you might have on this idea.
I have a 12v dc cordless drill motor and would like to control it with a joystick [forward, reverse, variable speed]. I’ll be using the drill battery as the power supply. I’m not sure which motor controller is needed. My best guess is the Pololu Simple High-Power Motor Controller 18v25? Also once I find the correct controller how do I connect a joystick [10k pot ps2 style]? Can I connect it directly to the controller or Would Arduino Uno + Joystick shield kit work?

The SMC 18v25 should work (you might be able to get by with a lower-power version, but I cannot really give advice on that without knowing more about your motor). You can connect a potentiometer directly to the SMC (see section 4.4 of the SMC user’s guide).
