Simple robots, tank drives, small conveyor belts, and learning. It's cheap ($3–$5). hw 130 motor control shield for arduino datasheet
Integrated pull-down resistors keep motors disabled during the Arduino's power-up sequence to prevent erratic movement. User Review: Pros & Cons // Define pins based on HW-130 hard-wiring int
All are functionally identical to HW-130. User Review: Pros & Cons All are functionally
The shield's functionality is built around three primary integrated circuits: Dual L293D Motor Drivers
