Hw 130 Motor Control Shield For Arduino Datasheet Better -

To use the HW-130 shield, it is highly recommended to install the . The shield is not directly controlled through simple digitalWrite commands due to the shift register; the library handles this complexity for you.

Some revisions of the HW-130 route ENA/ENB to Analog pins A0/A1 or require jumpers to be removed to access PWM. If your motors run at full speed regardless of code, check if ENA/ENB are hard-wired via jumpers on the board. hw 130 motor control shield for arduino datasheet better

The HW-130 uses two L293D dual H-bridge chips and one 74HC595 shift register to expand the available control pins. L293D Based Arduino Motor Shield To use the HW-130 shield, it is highly
