🚀 Trapezoidal Motion Profile on Arduino Mega 🛠️
In this demo, a tiny DC motor with a 14 CPR quadrature encoder is driven through a 298:1 gearbox using a simple trapezoidal speed profile — accelerate → cruise → decelerate — all generated on an Arduino Mega with PWM control.
The encoder feedback is read using fast port access on pins 2 & 3, while the LCD displays live motor and output RPM, direction, and step progress.
The result: smooth, repeatable indexing moves without overshoot, even at over 2 600 RPM on the motor shaft.

⚡ Key features:

Quadrature decoding on external interrupts (Mega-friendly)

PWM trapezoidal profile on pin 5 via BC337 transistor

Fixed-distance indexing with dwell between moves

Live RPM + motion state feedback on a 4×20 I²C LCD
