Approx. 4W (with proper cooling) 3. Pinout & Hardware Layout The HW-130 sits directly on top of the Arduino Uno. It uses the following Arduino digital and analog pins (note that analog pins A0–A5 are broken out for general use ): Dedicated Motor Pins: | Motor | Direction Pin (Arduino) | PWM Speed Pin (Arduino) | |-------|------------------------|-------------------------| | M1 | D12 | D5 | | M2 | D11 | D6 | | M3 | D8 | D9 | | M4 | D7 | D10 |
void setMotor(int speed, bool reverse) digitalWrite(M1_DIR, reverse ? HIGH : LOW); analogWrite(M1_PWM, constrain(speed, 0, 255)); hw 130 motor control shield for arduino datasheet
