I know electrical and electronic circuits. I can design, simulate and create PCB boards, schematics, and layout for analog, digital, embedded, and power circuits. I have done many projects using Raspberry Pi, ESP32, Arduino, ARM, and PIC microcontrollers and many other MCUs. I have very good knowledge of WIFI, Bluetooth, SPI, UART, Serial and many other communications protocols. I have used Cam modules, NFC modules, IMU sensors, SIM modules, UWB modules, Fingerprint Sensors, and many other peripheral devices in my projects. Check some of project that I have done: ➣ NFC Fingerprint Key and Lock: In this STM32 MCU is used along with Bluetooth, NFC, storage, and security modules. A fingerprint sensor is used along with an NFC chip for the lock and unlock mechanism. I have done all the work from Circuit design, PCB layout to Programming. ➣ Vibrational Phone Cover: It had 12 vibrational motors was controlled by an ESP32 that was connected to the android phone through Bluetooth. Each of the 12 motors and their speed were controlled individually by phone through Bluetooth. ➣ NFC card password protection: In this Raspberry PI and PN532 card reader is used along with an RPI cam module to put data (URL) from the QR code to the NFC tag and password protect it. ➣ Moving Dot : In this, a Aim of a Gun is displayed on a transparent AR display. So that user can get where the Gun is aiming. In this IMU sensors with a Raspberry Pi Zero are used to detect the orientation of the gun, and Bluetooth and I2C were communication protocols in it. ➣ Laser Mouse : In these Android Phone is used to control the Mouse of PC. The mouse position can be controlled either by the changing orientation of the Android device or by the mouse pad on the Android device. The WIFI TCP protocol is used for communication. The whole Android and PC work, from building a test app to publishing it on the Google Play Store, was done by me. Android Studio is used to develop Android apps, and PC-side server apps are designed using Python. ➣ Bluetooth Speaker: The ESP32 is used to stream sound through Bluetooth, and a WS2812b RGB led was attached to it and programmed to react to music. ➣ Image Processing: Developed Python Program to Count Number of Cars on the Road using a Cam Stream from Raspberry Pi Cam to Control Traffic Lights. ➣ Bluetooth Hub: In this I Designed a PCB using Multiple Esp32, It was a Bluetooth Hub that get Input Sound Stream from Any Bt Audio Source and transfer it to multiple Bluetooth Speakers. Using this multiple Bluetooth Speaker Can be played by One Bluetooth sound source. Provided functionality to sync speakers, Adjust Volume and add or remove Bt Speakers. I have done many projects in WIFI and Bluetooth communication and have very good knowledge of Python, C++, C#, Java, and MATLAB. I make PCB boards schematic and layout design in Autodesk eagle. I know assembly language programming and have work experience with pic microcontrollers and MPLABX IDE.
