Digital code Lock System
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.

A Light Activated Motor Controller using IC 555 is a simple electronic circuit that turns a motor ON or OFF based on the presence or absence of light. It uses a LDR (Light Dependent Resistor) as a light sensor and the 555 timer IC in a comparator mode, along with an LED to indicate the motor’s status.

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.

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.
