This is a smart lift project for students in electrical engineering for their practice today and tomorrow is the requested picture and send me the address and cheaper than dirt bike gear and cheaper than ndege you want 66g good morning I hope you had a great day today love you too mines in electrical system for the day and I am good with that one is a smart tv to wifi inaitwa outer banks Netflix and chill with you and your family are you doing today I am not sure if you have any questions ililetwa na na na na na na na na na na na na na surprise you with you and I will be there at 7

1. Lift System
GROUP 9

2. INTRODUCTION

Overview of the project: Design and implementation of a cost-effective
3-floor lift system.

Use of ESP32 microcontroller and other affordable components.

Objective: To develop a functional lift prototype with basic automation
and safety features.

4. System Components

Microcontroller: ESP32 (for control and communication).

Input Devices: Push buttons for floor selection.

Sensors: IR sensors for detecting floor positions.

Door Mechanism: Servo motor for automatic door opening and closing.

Motor & Driver: DC motor with motor driver for lift movement.

Display: Small OLED screen for floor indication.

Cushion Mechanism: Spring or foam at the bottom for emergency
impact absorption.

Power Supply: 5V/12V power supply.

5. Structural Design

Cabin Material: Plywood for lightweight, cost-effectiveness, and
durability.

Support Frame: Metal rods or wooden beams.

Pulley System: Uses a simple rope or belt mechanism.

Emergency Cushion: Spring or foam at the bottom to absorb
shock in case of failure.

Door Mechanism: Sliding or hinged door controlled by a servo
motor.

7. Working Principle

The user presses a push button to call the lift to a specific
floor.

The ESP32 processes the request and moves the lift
accordingly.

IR sensors detect when the lift reaches the desired floor
and stops the motor.

The door automatically opens using a servo motor.

The display shows the current floor.

10. Circuit Diagram

Circuit Components: ESP32, motor driver (L298N), DC motor, IR
sensors, push buttons, servo motor for the door, and power supply.

Connections: Push buttons connected to ESP32 for user input; IR
sensors for floor detection; motor driver controlling the motor
movement; servo motor controlling the door.

Implementation: The circuit is tested on a breadboard before final
assembly. Each component is verified for proper operation.

Expected Outcome: The lift moves smoothly between floors with
accurate stopping points, and the door opens and closes
automatically.

12. Software Development & Testing

Programming the ESP32: Writing and testing firmware for motor control, sensor
handling, and door operation.

Simulation & Debugging: Using simulation tools to refine control logic.

Testing Steps:

Testing motor responsiveness to button presses.

Verifying IR sensor accuracy in floor detection.

Ensuring the emergency mechanism works as expected.

Checking servo motor functionality for door operation.

Observations: Identifying response times, motor movement efficiency, door
operation timing, and safety features.
