// SPEED=1..20 maps to PWM duty via a geometric curve from MIN_DUTY (s=1) to 255 (s=20). // SPEED=0 stops the motor. Stopped -> running triggers a 10s full-duty cold start. const int MIN_DUTY = 42; // ...

This project implements a DC motor speed control system using Arduino and an L298N motor driver. The motor speed is measured using an IR sensor acting as an encoder, and a PI controller is used to ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...
