Electronic method in measuring particle motion / Mior Yusof Mior Othman and Sharulnizzat Ismail

Our project is about “Electronic Method In Measuring Particle Motion”. This electronic device use to measure velocity and acceleration of moving body. In physical aspect, a moving body creates their own velocity and acceleration. The value of this particle motion can be calculated by Newton’s Law of motion which state that v = s/t and a = v/t. Our device count the time taken by a body that moving through a two points which the distance between them are already fixed to 100cm. Our circuit operates in digital condition which the sensitivity is very high since the circuit only works at two states, LOW and HIGH. Otherwise this circuit also consist of analog part which stands for start counting point and end counting point that establish by the LDRs , LEDs and NPN bipolar junction transistor. This project can be used in industrial application such as mechanical instrument. The velocity and acceleration is important thing in completing mechanical devices.
