Project Title 1: Attendance and access control System

• Project Description: Attendance control device having display is used to record the attendance in school and factory and give access to users according to time zone and troubleshooting the issue faced. Here we have used Linux Interface with RF Card module using i2c Communication and Wiegand protocol.
• Responsibilities:
• Developed and implemented firmware solutions for embedded systems using ARM Cortex-M4 processor.
• Designed, coded, tested, and debugged system software while optimizing and maintaining existing firmware codebases.
• Developed firmware to interface RF card readers with the STM32 microcontroller using I2C communication and the Wiegand protocol.
• Integrated Wiegand protocol for processing access control data.
• Enabled and optimized I2C ports on the SoC for seamless data transmission.
• Implemented data handling mechanisms to transfer access control data from STM32 to the processor via I2C, triggering relay-based door access.
• Implemented the GUI for the device frontend, enabling the display of menu images on the device screen for user interaction.
• Developed and maintained comprehensive firmware documentation, including maintenance processes and troubleshooting procedures.
• Debugged firmware and custom hardware platforms, developed low-level hardware interface drivers, and optimized firmware performance.
• Delivered SDKs and APIs to support customer integration of embedded products.
• Established reliable TCP/IP communication for transferring stored attendance data from
• Tools Used : JIRA. Eclipse, Git, Putty, Linux

Project Title 2: Cafeteria Management System.

• Project Description : This System is using for taking token for food at office, schools, factory etc.
• We designed Main window for showing the menu, price and timings and generating different windows for each time zone.by using this window we will get the printed token and we will get the access also.
• Responsibilities:
• Created windows for cafeteria management system by using MINIGUI
• Assigned time zone for breakfast lunch dinner.
• By using the unique id of each person setting to enter to the device .

• Assisting in product design for developing the production of electronics appliances and robotics design Gave the guidance to the students for specialization project that is based on Arduino developing board and gave the instructions for programming the same.
• Designing of PCB Board and assembling components.

• Conducted robotics class for school students as the part of STEM based learning
• Lead the robotics department and assisted in electronics related projects Conducted robotics workshops on various engineering collages and schools.
• Created Arduino based demo models of various robots
