This work involves the design and demonstration of a pulse rate monitoring system in real time. The goal of this project is to construct an integrated system that monitors the pulse rate through a finger via IR and provides the pulse rate in beat per minute (BPM) and displays it through LCD. We used a pulse sensor when a finger is placed on it, the reflected light changes according to the amount of blood in the capillaries. This change in transmission and reflection of light can be obtained as a pulse from the output of the pulse sensor.

Peripheral Interface Controller-based Digital Capacitance Meter.

In our project, we developed a capacitance meter leveraging the PIC16F628A microcontroller, aimed at accurately measuring unknown capacitor values. Traditionally, RLC meters have been used for capacitance measurement, dating back to 1960. However, the need for reliable capacitors emerged in the late 1800s, with the inception of the Leyden Jar in 1745-46. Our system utilizes the microcontroller's analog comparators and TIMER2 module to charge a capacitor, measure voltage level change over time, and calculate capacitance precisely. This cost-effective solution offers high accuracy and versatility for electronic applications, showcasing construction, performance evaluation, and practical usage analysis.
