2).  Smart Cup

Brief: Smart Cup measures the amount of liquid consumed by the user and transmits
the data to the cloud via the LoRa module.

Work Responsibilities:

• Developed firmware for the STM32L0 to interface various sensors, such as an accelerometer, a temperature sensor, and a capacitive sensor.
• Developed state machine in accordance with product specifications.

Technology used:

Embedded c, SPI,I2C,LoRa

3). Array quadrant controller

Brief: It is a component of the Akash NG missile's multifunctional radar's active antenna
array unit. The array quadrant controller is used to control, communicate, and control the transmitter and receiver antennas.

Work responsibilities:

• Developed firmware for communicating 360 (no.) transmitter/receiver modules via SPI protocol for the Arm cortex M-4 microcontroller TM4C1294NCPDT. It examines the
  link status of the transmitter and receiver modules, chooses whether to enable the transmit or receive modes, and sends data from the radar computer to produce the radiation pattern.
• Developed firmware for the Array power controller unit, which updates the on/off status of transmitter/receiver modules.
• RF Testing of system and providing support to client team from DRDO

Technology used
Embedded c, SPI,modbus,UART,I2C

4). Smart wallet
Brief: The smart wallet was a device with a fingerprint sensor (ARA-EM03) and GSM
(SIM800C).To unlock the wallet and enroll fingerprints, a fingerprint sensor was used.
GSM was utilized for real-time tracking.
Work responsibilities

• Developed firmware for communicating Cypress BLE(CYBLE022001) with fingerprint sensor and SIM800C
• Developed firmware for communicating between a mobile app and a microcontroller via Bluetooth low energy.
• Device testing and support for client CEEL

Technology used
Embedded C, UART,FreeRTOS,BLE

5). Smart card reader
Brief: The smart card reader is based on the NXP PN7462 and can read both
contactless and contact smart cards such as mifare ckassic and mifare desfire.
Work responsibilities:

• Developed firmware for the smart card protocols ISO7816 and ISO14443
• Developed firmware for communicating TDA8026 with PN7462 (Arm cortex M0) for simultaneous reading of multiple smartcards via I2C protocol.
