An adjustable potentiometer, 10K Potentiometer Module can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot.
A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal.
This is a 2 Channel isolated 5V 10A relay module Optocoupler for Arduino PIC ARM. It can be used to control various appliances and other types of equipment with a large current. It can be controlled directly with 3.3V or 5V logic signals from a microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).
It is a 4 Channel Isolated 5V 10A Relay Module, A wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on can control it. It is also able to control various appliances and other types of equipment with a large current.
This is JoyStick Module PS2 Breakout Sensor very similar to the ‘analog’ joysticks on PS2 (PlayStation 2) controllers. Directional movements are simply two potentiometers – one for each axis. Pots are ~10k each. This joystick also has a select button that is actuated when the joystick is press down.
This is a small and easy to use 1 channel relay board that operates on 12V. Use it to control one 240V power appliance directly from Arduino, Raspberry Pi, and other microcontrollers or low voltage circuits. Perfect for switching 240V appliances – lights, fans, etc, and even high power motors at lower voltages.
The M274 360 Degree Rotary Encoder Module Brick Sensor is a rotary input device (as in knob) that provides an indication of how much the knob has been rotated AND what direction it is rotating in. It’s a great device for stepper and servo motor control. You could also use it to control devices like digital potentiometers.
This JoyStick Shield Module Robotics Control is an Uno compatible shield that allows you to turn an Arduino Uno or compatible into a game console or robotic controller. 3.3V to 5V Gamepad Joystick Shield Module Game Rocker Button Controller Expansion Board For Arduino Simulated Keyboard Mouse Module
