Abstract
This paper elucidates simple design method of a low cost digital velocity meter based on PIC16F77A microcontroller. This digital velocity meter identifies the linear velocity of any fluids as well as any kind of movable objects. LASER and light dependent resistor are two cardinal sensors to design this meter. By this sensor any moving object or moving fluid's initial and final time is calculated at a certain distance. An electrical switch measure this time duration of certain distance very precisely. With this input signal by using the velocity formula the single chip microcontroller compute the velocity. Then the computed formats of velocity are displayed in a 16×2 character LCD. It also shows the time duration of objects to pass the two sensors. This design process is more effective than others as it is more economical, efficient and simple.
