Lissajous pattern generator for beginners

myminifactory

Two tiny DC motors featuring a circular mirror attached to the shaft at an angle are struck by a 5V laser beam. The motor sizes can be adjusted in the SCAD file, where they are clearly labeled. By adjusting the speed of one motor, intricate Lissajous patterns are projected onto the ceiling. The motor diameters are easily adjustable in the SCAD file, where they are prominently displayed. If you run this with an Arduino board, try using these settings: int M1 = 0; int M2 = 1; void setup() { pinMode(M1, OUTPUT); pinMode(M2, OUTPUT); } void loop() { analogWrite(M1,255); analogWrite(M2,200); delay(100); }
