    "abstract": "We describe a 8085 microprocessor interface developed to make reliable time\nperiod measurements. The time period of each oscillation of a simple pendulum\nwas measured using this interface. The variation of the time period with\nincreasing oscillation was studied for the simple harmonic motion (SHM) and for\nlarge angle initial displacements (non-SHM). The results underlines the\nimportance of the precautions which the students are asked to take while\nperforming the pendulum experiment.",
