Abstract

Physics experiments have a very important role. The most important thing that must be considered in performing experimental physics experiment is set. The development of digital experiment set not completely perfect, like a set of simple harmonic motion experiments on the spring. This study aims to determine the performance specifications and design specifications set of experiments manufacture simple harmonic motion sensors based on spring ping and photodioda with LCD display and PC. This research was a laboratory experiment. Set the experiment uses Arduino Uno microcontroller which serves to process the output of the sensor and change the sensor output with the expected output display measurement results of the experimental set of simple harmonic motion in the spring using the LCD and PC. The sensor used is a ping sensor yng function calculates the amplitude and photodiode sensors that function to count the number of oscillations in the spring time (ms). Besides this experimental set period has accuracy with accuracy percentage is 96.16% for a single spring arrangement, 96.40% for the composition of the spring series, and 99.25% for the parallel spring arrangement. While the average percentage error obtained is 3.69% for a single spring arrangement, 3.59% for the arrangement of the spring series, 0.74% for the parallel spring arrangement.Keywords : Arduino Uno microcontroller, photodiode sensor, ping sensor

Abstract

This paper discus about the forced oscillation with damping which it is simulated by using Excel Spreadsheet and Macro Visual Basic For Application.  The system was considerating  as a string with mass m  where it oscillates on  the influence of force and damp. The Equations of forced oscillation with damping processes  in spreadsheet excel and  simulates  using  Macro Visual Basic For Application approached.  To verify the accuracy  we use  the numerical solution of Heun and Runge-Kutta Merson methods, the two-order differential equations are converted to first order linear differential equations and then look for algorithms for each numerical method. Algorithm of numerical method of input, process and output.  This paper also shows that Runge-Kutta Merson  numerical method has higher accuracy than Heun numerical method in solving the equation of forced oscillation with damping.Keywords: Numerical Solutions, Excel Spreadsheet,  Visual Basic For Application
