Switches

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.

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.

Applications:

1.As square wave signal generator which generates a square wave signal

2. To provide a signal to the stepping motor driver

3. Adjustable pulse generation for chip use

4. Produce variable pulse signal, the control-related circuit (PWM dimming, speed)

Module Description:

Frequency is divided into three ranges:

1.XXX (no decimal point):the smallest unit is 1Hz,the range 1Hz-999Hz

2.XX.X (decimal point in ten): The minimum unit is 0.1Khz; the range of 0.1KHz-99.9KHz

3.X.X.X.(there is three decimal point): the smallest unit is 1Khz; the range 1KHz-150KHz

Frequency Display Example:

1.”100″ indicates that the PWM output pulse of 100Hz

2.”54.1″ indicates that the PWM output pulse of 54.1KHz

3.”1.2.4.” Indicates that the PWM pulse output 124KHz

4.Duty Cycle in the range:0 to 100

5. Three frequencies duty cycle is the same, all the parameters non-volatile

Features:

1. 2.54mm pin interface leads
2. Long service life and stable performance
3. Standard interface and electronic building blocks
4. Widely use in Arduino DIY projects
5. Cross rocker as a two-way 10K resistor, with the rocker in a different direction.

The USB to RS485 TTL Serial Converter Adapter FT232 Module is USB2.0 standard, backward compatible, in line with the standard RS485. It has Direction control with use of automatic data flow control, auto distinguish and control data transfer direction with Baud rate of 300-9216000bps and automatically detecting the serial signal data rate.

It supports the multipoint, each converter allows the RS485 interface device to connect 32 and comes with TVS tube Interface Protection and also with USB self-recovery protection.

This USB to RS485 TTL Serial Converter provides two-way serial communications signal conversion between the RS485 to and from a personal computer USB port using virtual serial COM port. Self-powered from USB it uses FT232RL+75176 and can have up to 32 devices on the bus.

The 4 jumpers connect the USB interface to the RS485 interface. If the jumpers are removed, the USB interface may be used as a TTL Level Serial port.

Some of the Applications are:-

1. Surveillance Cameras
2. Video capture device
3. Fingerprint attendance machine
4. PBX
5. CNC machine

Features:-

1. Load capacity: support multipoint, each converter allows RS485 interface device to connect 32
2. Interface Protection: TVS tube protection, USB self-recovery protection
3. Support Windows98/ME/2000/XP/WIN7/Vista, Linux, Mac
4. Self-powered from USB.
5. It can be up to 32 devices on the bus.
