• Car Black Box, Black Boxes are typically used in any transportation system (ex: Airplanes) that are used for analysis post-crash and understand the root cause of accidents. Continuous monitoring and logging of events (ex: over-speeding) is critical for effective usage of black box. The goal of this project is to implement core functionalities of a care black-box in a PIC based micro-controller supported by rich peripherals. Events will be logged in EEPROM in this project. This project can be further extended to any vehicle., PIC micro-controller & schematics, Peripheral (ex: Potentiometer) handling by understanding data-sheets, Interrupt handling, Programming the PIC microcontroller efficiently and effectively for continuous monitoring and logging., Understanding and integrating various peripherals like potentiometers based on their datasheets., Implementing reliable data logging in EEPROM, ensuring data integrity and efficient storage management., Gained deep knowledge of PIC microcontroller programming and schematic design
• Inverted Search, The purpose of storing an index is to optimize speed and performance in finding relevant documents for a search query. Without an index, the search engine would scan every document in the corpus, which would require considerable time and computing power., Hashing, Single linked list, Implementing and managing a single linked list for storing the index data required careful handling of memory allocation and deallocation, as well as ensuring efficient insertion, deletion, and traversal operations, Understanding and applying hashing techniques to store and manage the index.
• Image Steganography using LSB Encoding and Decoding, The objective was to send a secret text file encoded inside an image of bmp file format. Encoded the length of the secret text and then encoded the data into the LSB of the image bytes. The decoding process involves decoding the length and then decoding the text bit by bit. The final output is the secret text after decoding., Embedded C – File operations, Pointers, Bitwise operations, Functions, Makefiles, Command line arguments, Understanding of pixels and header of image file by doing literature study, Transforming the embedded information to the destination without changing properties of original image, Faced challenges while doing bitwise manipulation of data to embed as well to retrieve the data from the destination image which was solved by self-understanding.
