// 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 controls the speed and direction of a DC motor using an Arduino, a potentiometer, and two push buttons. It requires an L293D motor driver IC to function. Functionality ⚙ This program ...
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 ...
