Sin Wave Plotter

Introduction: Sin Wave Plotter

The sine wave plotter is a design made to help demonstrate the sine function wave, that we made to help students in a Vietnamese school. Some of the restraints that we need to keep in mind is that the prototype must be light in weight and made of recyclable materials (MDF Wood and PLA). The prototype should also show the difference between two waves of varying amplitude.
