16. Remote Password Security
This is one of the interesting Android projects. Security is a crucial matter for all, be it regarding private property, or commercial property, or intellectual property. Security breaches not only lead to the loss of sensitive data but also lead to significant financial losses. This remote password security project is a system where only an authorized user can change the password, as and when required.
In this security system, one can change the password remotely by using an Android application from an Android device. The Android app will offer an interactive GUI for the system that is operated via an 8051 microcontroller.
The user password will be stored in an EEPROM. Once you enter the password via the Android app, the Bluetooth receiver will pick up the signal and forward it to the 8051 microcontrollers which will process it, verify its validity against the user’s stored password. If the verification is complete, the system will unlock.
17. Password-based Circuit Breaker
This is one of the trending Android projects. When electrical accidents occur, they pose a threat to the safety of linemen who take great risks for repairing the issue with electrical lines. This is primarily due to a lack of clear communication between the maintenance staff and the electrical substation. This project seeks to address the issue of linemen safety by creating a password-cased circuit breaker that can control electrical lines by using a password.
The core component in the circuit of the password-cased circuit breaker is an 8051 microcontroller. In this password-based system, the control (on/off functions) of the electrical lines lies with the linemen. So, before starting to work on electrical lines, linemen can enter the password to cut off the electrical connection on the particular line.
After the repair is done, they can resume the connection by re-entering the password. In the proposed system, each electrical line will have a unique password to avoid confusion. The load (Light Bulbs) indicates the activation and deactivation of the electrical lines (circuit breaker).
18. Firefighter Robot
Fire fighting is a risky business. Firefighters are always at the risk of burning, scorching, and suffocating in the fire when they are on rescue missions. This project is designed to promote unmanned firefighting by creating a robot that uses Bluetooth, an Android application, and a microcontroller to function. This is one of the interesting Java projects.
It works something like this – the Android application installed in the Android device will send commands via Bluetooth to the receiver module connected to the microcontroller of the robot. These commands can move the robot forward, backward, or in the right and left directions. The receiver part of the robot includes a Bluetooth receiver, a Bluetooth decoder, a microcontroller, a relay, and two motor drivers.
Once the Bluetooth receiver gets the signal transmitted by the Bluetooth transmitter in the Android device, it decodes the signal. The decoded signal is then further processed by the microcontroller, which then drives the motor according to the signal received and moves the robot. The user can also control the movement of the water sprinkler nozzle.
19. Antenna Positioning System
You will design an Android-based antenna positioning system that can position the antenna by using an Android application. This allows the antenna to point straight towards the device sending the signal.
The antenna positioning system uses an 8051 family microcontroller and LCD screen to display the status of the antenna’s angle. A 12V transformer powers the system. The user can send the appropriate commands to move the antenna via the Android application. A Bluetooth receiver modem receives these commands and moves the antenna based on the input parameters provided.
There are precisely three input parameters:
- The first parameter step determines the angle in which the antenna should move.
- The second parameter specifies whether the antenna should move in a clockwise or an anticlockwise direction.
- The third parameter determines the speed in which the antenna should move. The speed parameter includes L for low, M for medium, and H for high speed.
This project involves the creation of a hovercraft that can be controlled via an Android application. The Android app sends commands to the hovercraft circuit for moving the device. The circuit comprises a Bluetooth receiver that receives and processes the commands. The commands received by the Bluetooth receiver are further processed by the microcontroller, which dictates the final movement of the hovercraft.
The hovercraft you will design will require high RPM motors interfaced with an AVR family microcontroller to achieve the desired functionality. There are three motors involved in the design of this hovercraft. The motor situated below the hovercraft rotates at a very high RPM, thereby imparting to it enough force so it can hover above the surface level.
The friction remains at a minimum. A motor propeller is mounted behind the hovercraft to allow it to move in the forward direction. The servo motor attached to the hovercraft rudder helps it to move in every direction by bending the air at accurate angles.
