One of the best ideas to start experimenting you hands-on Android projects for students is working on Android based Function Generator. This Android-based function generator features an output range of audio frequency signals around 20Hz-20,000Hz emitted through the audio port of mobile phones (usually, 3.5mm audio jack). The functions available on the Android-based function generator include sine wave, square-wave, triangular-wave, and saw tooth-wave, all within the 20Hz to 20,000Hz range. To test the signals generated by this function generator, you can use a digital storage oscilloscope and Windows PC-based CO software.php projects titles topics
You can amplify the signals using an amplifier if you want to interface the function generator with other external devices. However, you must ensure that you use an appropriate protection circuit to avoid damaging your mobile device.
The project includes relatively few electronic components and does not involve any intricate soldering. The core components are Arduino Uo R3 (Board1), three relays (RL1 through RL3), and the HC-05 Bluetooth module. The main goal of this project is to depict how to switch on/off electronic appliances that are connected via three relays using a smartphone/tablet with an Android app. Mentioning Android projects can help your resume look much more interesting than others.mca project topics
the light of ever-increasing security incidents, the demand for I smart home systems is escalating rapidly. Typically, IT- enabled home security solutions make use of different sensors to collect and share data from multiple devices. So, in any case, an outsider threatens to violate or breach the system, the underlying functional logic of the smart system will alert the owner of the property who can then take the necessary actions.
This project aims to build an IoT based notification system, including a fire alarm, door sensor, doorbell, and motion detector. Sensors used are a magnetic reed switch for a door or window, PIR sensor for motion detection, and an NTC thermistor for fire alarm. In case of a breach in your property, this IoT based notification system will trigger an event via its various sensors and send relevant notifications to your smartphone.android app ideas for students college project
