Computerized photo gate timer in physics Lab using MIAC
Introduction
Photo gate timer is a device used in physics labs to measure the time interval between two successive interrupts this time usually not exceed one second
The proposed experiments that photo gate timer can be done are so many experiment like
Experiment 1: Instantaneous vs Average Velocity
Experiment 2: Kinematics on an Inclined Plane
Experiment 4: Newton's Second Law
Experiment 5: The Force of Gravity
Experiment 6: Conservation of Momentum
Experiment 7: Kinetic Energy
Experiment 8: Conservation of Mechanical Energy
Experiment 9: Elastic-Kinetic Energy
Experiment 10: Pendulum Motion
There are many types of measuring instrument to measure the interval of time in physics lab these known as photo gate timer one of them produced by Pasco company

Here I used MIAC as an interrupter device to start the timer or ended it by using a photo gate sensor of infra red detector
The interface computer window was designed by C# to achieve all steps that the student's physics lab need like pre designed table for each experiment with ready to receive the interrupt signal coming from MIAC and start the timer a display timer with all units from Hours to microsecond
The application start with the choosing the title of the experiment to proceed and the number of rows or trials of the selected experiment
Each table contain four types of data
1-sensor data entry i.e. the interrupt signal which initiate or terminate the timer
2-humman data entry
3- constants
4-calculated data
the data calculated can be done by using predefined and preserved equation as library for all most known physics and mathematics formula
there are three mode of time measuring
1-gate mode
2-pulse mode
3-pendulum mode
After filling the table with different data
