Introduction

In this project, we will make a 4 digit passcode safe lock using the Ps2 joystick module and 16*2 Lcd display. We will move the joystick in x and y direction to increase or decrease the value from 0 to 9 and other to move the joystick in up and downside to move the cursor in both left and right direction which is displayed on the display.

HARDWARE REQUIRED

SOFTWARE REQUIRED

Arduino IDE 1.8.5 (programmable platform for Arduino)

Click To Download:https://www.arduino.cc/en/Main/Software

SPECIFICATIONS

Joystick Module

Supply Voltage: 3.3V to 5V
Interface: Analog x2,Digital x1
PH2.0 Interface
Size:35x39mm
Weight:15g

**16*2 LCD**

Standard 16×2 Character LCD
16 Characters Wide x 2 Lines
5 x 8 Dots with Cursor
Built in Controller (HD44780 or equivalent)
+3.3V Power Supply
Backlight Included

PIN DESCRIPTION

Joystick module

10k potentiometer

**16*2 LCD Display**

CIRCUIT DESCRIPTION

NOTE – here we are using a 10k potentiometer but as shown in the figure, the resistor going from 5v and GND to the LCD pin3 V0 replace the 10K potentiometer. You can use 1k ohm from 5v and 330 ohms going down to GND but you may use different resistors or pot depending on the LCD, But for the convenience, we are using 10K pot.

Joystick Module – Arduino Uno

Joystick module has 5 pins gnd, vcc,vrx,vry,sw

NOTE – Here this switch pin on Joystick must be connected to a digital output pin mode. if not then it doesn’t give accurate readings so best to use digital pin 13 here.

WORKING

Plug the supply to Arduino UNO after uploading the code you see the text on display enter the code
Now you enter the code using the joystick movement left to right to change the cursor position
Move the joystick Down and up to change the number.
Now set the number as mentioned in the code (you can change in the code ). Now press joystick after taking in the center position so you can see the REES52 Lock on (You can customize it) password on the LCD display.
