Arduino – Draw Shapes on OLED Screen

You can draw and overlap custom shapes on OLED screens to provide your users with a better User Experience.

display.drawLine(StartX, StartY, EndX, EndY, WHITE);

display.drawRect(StartX, StartY, Width in Pixels, Height in Pixels, WHITE);

display.drawCircle(CenterX, CenterY, Radius in Pixels, WHITE);

display.drawTriangle(FirstX , FirstY, SecondX, SecondY, ThirdX, ThirdY, WHITE);
