Built an 8-bit SAP (Simple as Possible) microprocessor with specified instruction sets using Proteus software.
In this project, we have built a system using Arduino that can control the temperature of a room automatically according to the desire of the user. It use temperature sensor for the measurement part. We used are cooling and water cooling to decrease the temperature if it became above the threshold. An electric bulb was used if the temperature went below the desired value.
This project was all about making a calculator with certain requirements using Op-Amps in PSpice. The calculator had four operations: Division, Multiplication, Exponent, Square Root. We used 74157 Multiplexer IC in this project as it was required by our respected course teachers. There were two DC inputs. Using these inputs, we had to do the mathematical operations as mentioned above. If we want to do certain operation, then we just need to turn on the specific node of the multiplexer. And after that, the output node will show the output.
In this project, we were given a +5 volts DC source. The requirement was to generate -5 volts DC at the output terminal where the output ground should be shorted with the input ground. We were allowed to use only one IC that is LM-7805 to have a constant input of 5 volts DC. To do the job, we designed an Astable Multivibrator to generate AC voltage from the DC input. Voltage multiplier circuit was used in order to increase the voltage and convert the AC to DC having a negative sign. Then we used voltage divider to get our desired output.
In this project, we simulated a wireless data transmission system in MATLAB that can transmit text, audio and image data using Orthogonal Frequency Division Multiplexing (OFDM) through a multipath Rayleigh fading channel. For modulation, 16-QAM (Quadrature Amplitude Modulation) was used. Convolutional Coding was used for error correction coding and Viterbi algorithm was used for error correction decoding.

In this project, we developed a machine learning based system to control the access of a door and lighting using a Raspberry Pi. A machine learning based facial recognition algorithm utilizes the processing capability of a Raspberry Pi to detect and identify individuals. Authorized individuals—those whose facial data is stored in the database—are displayed on a custom GUI (Graphical User Interface), where their access can be managed via checkboxes. Access is granted only if the person's face is recognized and permission is enabled in the control panel. We connected a relay to the Raspberry Pi which was used control the door lock system.
We built a prosthetic hand using EMG sensor (Myo Sensor), Servo Motor and Arduino. We made the hand using wood. We detected movement of hand using the Myo sensor and sent the signal to Arduino. Then Arduino sent signal to servo motor which was used to move the hand and fingers of the prosthetic hand.
In this project, we used Digital Signal Processing to measure the velocity of vehicle from its engine sound in MATLAB. Our approach was based on the Doppler Effect. We used an algorithm which we got from a paper.
Our objective was to build a monitoring system that will help the doctor monitor patients' heartbeat and temperature remotely. We used Heartbeat Sensor, Temperature Sensor, ESP8266 Microcontroller, MATLAB and a Cloud Server to do this.
In this project, we were tasked to rewind a 3-Phase Induction Motor. So, we bought a 3-Phase Induction Motor and cut it's coils. Then we rewinded the coils of the motor.
In this project we implemented our previous software project in hardware. This hardware implementation required modification from the software one.
This project addresses the problem of harmonic current and an efficient way to cancel the currents which includes usage of Solar PV cell as Shunt Active Power Filter(SAPF)
In this project, we implemented our knowledge of digital electronics to make a game where the player will try to catch falling lights with a row of White LEDs called the players row. We used another 8x8 matrix of LEDs for the game. All the LEDs of the 8x8 LEDs were RGB. We generated different colors of light randomly. Different colors of light have different points. Catching lights will increase the points. The player has a certain amount of lives. If the player misses a light, his lives will decrease. If his life becomes zero, the game will freeze. Thus the game will continue.
