FSRs are sensors that allow you to detect physical pressure, squeezing and weight. They are simple to use and low cost. This sensor is a Interlink model 402 FSR with 1/2 diameter sensing region.

Introduction
The joystick PS2 module two lines of analog output (X, Y) and one of digital output (Z). The cross rocker is a bidirectional 10k resistor; its resistance changes with different directions. Push the joystick towards different directions and the voltage read increases or decreases; press it down, then the output is low level and the corresponding LED lights up; otherwise it stays off.
5-Pin anti-reverse cable included.

Application

Feature 

Thinking of control a moving robot by using a simple joystick, here it is. We carry analog joy stick that control front, back, left and right for your robot and a push button just in case. The default of x-pin and y-pin is 2.5 v. when the joystick push forward, the voltage increase untl maximum 5v and in the reverse (0v).

Description:

Rotation of the rotary encoder may be counted by the positive rotation direction and a reverse direction pulse frequency output during rotation potentiometer not count this rotation count is not limited. With buttons on the rotary encoder can be reset to the initial state, that starts counting from 0.

This particular module is suitable for tutorial use and perhaps for some hobbyists. Its drawback is that its I2C address is hard-wired to all zeros. (Note that I2C is a very effective 2-wire communications standard that is used by many small semiconductor devices such as microcontrollers and sensor peripherals.) If the address lines could be jumpered high or low, then several identical modules could be placed on the same I2C lines. I would therefore recommend the alternative module named the Mini PCF8591 AD DA Shell Module because it has that capability.
