  Joy stick PS2 Module Breakout Sensor,Dual Axis XY Joystick Module

  ₹60.00 Original price was: ₹60.00.₹39.00Current price is: ₹39.00. + GST

  • 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.

  Digital Magnetic Reed Switch Sensor SPST 2 Pins NO for DIY

  ₹20.00 Original price was: ₹20.00.₹14.27Current price is: ₹14.27. + GST

  • A reed switch consists of two ferromagnetic nickel-iron wires and specially shaped contact blades (reeds) positioned in a hermetically sealed glass capsule with a gap between them and in a protective atmosphere. The glass capsule is filled with inert gas to prevent activation of the contacts. The ruthenium or rhodium plated contact surfaces are isolated from the outside environment, which protects the contacts from contamination.

  This is a small 14 mm Reed Sensor.
