Digital code Lock System
In Stock
A digital code lock system with a buzzer and servo motor is an embedded project that enhances security. When the correct code is entered, the microcontroller triggers a servo motor to unlock a door or container. If an incorrect code is entered, a buzzer sounds as an alert.
Description
A Digital Code Lock System using the 8051 microcontroller is an embedded security project designed to control access based on a secret passcode entered through a keypad. The system is ideal for securing doors, cabinets, or any restricted area, and it operates by comparing the entered code with a pre-programmed password. If the correct code is entered, the system unlocks the mechanism, and if the wrong code is entered, it triggers an alert using a buzzer. This project provides a hands-on approach to learning microcontroller-based programming and interfacing with different components.

This project involves controlling a DC motor’s direction using an 8051 microcontroller, with a buzzer and LED indicating the motor’s rotation state. When the DC motor rotates forward, the microcontroller keeps the buzzer and LED off. However, when the motor is rotated in reverse, the microcontroller triggers both the buzzer and LED to turn on as a visual and audible indication of the motor’s reverse rotation

An Electronic Dice is a digital version of a traditional dice, which generates a random number (1 to 6) and displays it using LEDs or a 7-segment display. It uses components like a 555 timer, counter IC (like CD4017), or microcontrollers such as Arduino to simulate dice rolls electronically.

A Battery High-Low Monitor is an electronic circuit or device that detects and indicates the voltage level of a battery — whether it’s too high (overcharged), normal, or too low (discharged). It helps protect batteries from overcharging or deep discharge, which can damage the battery or reduce its lifespan.
These monitors often use comparators, voltage dividers, LED indicators, or microcontrollers to track and display battery status in real time.

- A rain alert system with an LCD display and buzzer, controlled by an 8051 microcontroller, is designed to detect rainfall and provide real-time notifications. The system uses a rain sensor to detect moisture or rainfall, and the microcontroller processes the sensor data. When rain is detected, the 8051 triggers a buzzer to alert the user audibly and displays the rain status on an LCD screen.

The Conveyor Belt Object Counter using LDR and 7-Segment Display with the 8051 microcontroller is designed to count objects passing in front of an LDR (Light Dependent Resistor) sensor. The system works by detecting light interruptions when an object crosses the sensor, causing a change in the LDR’s resistance. The microcontroller processes this change and increments an object count. The count is then displayed on a 7-segment display.
