Simple micro switch that can be used as a limit switch, as a drawer switch or whatever you'd like. It even support higher current loads, so you can switch motors or high power leds with it (hint hint).
The joystick on this module is very similar to the 'analog' joysticks on popular gaming console 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 pressed down. There are 5 pins on board: VCC, GND, X, Y and Button. Connect...
Potentiometer is one of the most useful basic components. This is a 10k dial type potentiometer with knob. It’s space-saving and user-friendly. You can read the actual resistance value via the straightforward knob without auxiliary instrument like multimeter. Each has been pre-calibrated. You can implement it into your circuit right out of the box.
A simple rotary encoder for all your projects.
It's like a potentiometer, but without end. It sends pulse to your microcontroller to let you know in which direction it turned. This version also has a button.
IBridge is a 4X4 key-pad shield with a 5110 Graphic LCD interface. It is compatible with Arduino and IFLAT-32, you can plug it on Arduino/IFLAT-32 board directly, and you can get the small development platform with keypad input and Graphic LCD display. 5110 lcd not included.
This is a 4-way arcade joystick of crystal ball, metal shell and 4 momentary switches. The 4 momentary switches convert your move into a set of 4-way signals so that would send direction commands to your project. Also, it is industrial-standard and heavy-duty designed and will be cool to control your robots or any other machines.
