Joystick Module This is a dual axis high quality JoyStick Module . It can be used to sense movements in 2 directions(axes). It also has a inbuilt switch which can be activated by pressing the stick.Directional movements are simply two potentiometers - one for each axis. Pots are ~10k each.  With the help of this Joystick Module, you can measure position coordinates on the X and Y axis by moving the "hat". It also contains a switch that is press-able by pushing the "hat".It also contains a switch that is press-able by pushing the "hat" down. Similar to the XBOX controller. The X and Y axes are two 10k potentiometers which control 2D movement by generating analog signals. When the module is in working mode, it will output two analog values, representing two directions. This module uses the 5V power supply, and value, when reading through analog input, would be about 2.5V, a value will increase with joystick movement and will go up till maximum 5V; the value will decrease when the joystick is moved in other direction till 0V. Joystick module biaxial keys use SONY Corporation PS2 gamepad buttons on the original high-quality  metal rocker potentiometer, analog output module and one ad hoc Road digital output interface, the output value corresponding to (X, Y) pairs axis offset which is of analog type; coordinate identifiers clear, concise, accurate positioning; using it can easily control objects (such as two degrees of freedom servo head ) movement in two-dimensional space, sensor expansion board connectors etc.  A joystick is an input device that consists of a stick that can be tilted in multiple directions to control an on-screen object. The most common use of a joystick is in video gaming. In a video game, the player uses the joystick to move their character around the game world. Joysticks can also be used to control other on-screen objects, such as a cursor in a word processing program. Joysticks are usually designed to be ergonomic and comfortable to use. They typically have a large number of buttons and controls that can be programmed to perform different functions. Joysticks come in a variety of shapes and sizes, and can be plugged into a computer via a USB port, or wirelessly connected. There are a number of different types of joystick modules available on the market. The joystick price in India ranges from around Rs. 30/- to Rs. 45/-. One can easily buy Joystick Online from Iotcart. Iotcart offers customers the ease of shopping from home for their needs. This joystick modules typically offer the best performance and features, such as multiple analog outputs, all the way to digital output, and X, Y-axis output for the two potentiometers. However, even the cheapest joystick modules can provide a good level of performance and functionality. Applications: Camera Pan/Tilt Control. Game Input/Control. Robot Control. Widely use in DIY projects. Package Includes: 1 x Joystick Module Specifications: Operating Voltage (VDC) 5 Dimensions (mm) 40 x 27 x 15 (LxWxH) Weight (gm) 10

Matrix 16 Button Keypad Module (4x4 Keypad) The 4 X 4 Matrix Keypad (RM0947) is a very simple one from have 16 tactile keys connected to the male headers across the resisters on the same board. It is very small and easy to carry. Its simplicity is hexadecimal to give the power to the keypad and connect the headers to the microcontroller's input port with whenever pin female connecting wire. When one tactile key is pressed its corresponding pin with Rows and column intersection gets high logic. The connection to the keypad is divided into rows and columns. There are four rows and 4 columns that provides HexaDecimal Output is generated whenever any switch is pressed. The hexadecimal generated can be sent directly to the control unit for logical operation.This 4 X 4 matrix keypad is compatible with most of the controller boards available on Iotcart.com that ranges from 8051 to Arduino Boards. Since the Output and the input of the keypad is digital in nature so, it can also be interfaced to motor driver circuit available on Iotcart.com. How it Works? First test whether any key is pressed down. Connect power to rows, so they are High level. Then set all the rows R1-R4 as Low and then detect the status of the columns. Any column of Low indicates there is key pressing and that the key is among the 4 keys of the column. If all columns are High, it means no key is pressed down. Next, locate the key. Since the column in which the pressed key lies is identified, knowing the line would finalize the testing. Thus, set the rows as Low in turns until any is unveiled accordingly – other rows will still be High. Now the row can be identified. Detect the status of each column in turns. The column tested Low is the one intersecting with the line – their cross point is just the key pressed.
