Description

using ESP32 to simulate a combination of two 1Hz sin waves perpendicular to each others. but different in phase to create a Lissajaus figure and display the result in LCD display. the program will keep changing the phase and amplitude depending on the phasestep and amplitudestep in the program. in the attached arduino sketch (1HZ-FinalLissajous.ino) I used
float phaseStep = PI /8; and int amplitudeStep =15;
if I used a different numbers the figures will change
