Better - Hw 130 Motor Control Shield For Arduino Datasheet
HW-130 Motor Control Shield is a popular, low-cost "plug-and-play" driver based on the classic
// Motor B #define ENB 5 #define IN3 11 #define IN4 10 // Note: Some HW-130 use pin 8 for IN4 – verify continuity. hw 130 motor control shield for arduino datasheet better
Resolution: Offers individual 8-bit speed selection (approx. 0.5% resolution). Key Hardware Features HW-130 Motor Control Shield is a popular, low-cost
Electrical characteristics (practical values) Jumpers: There are often small jumpers near the power pins
- Jumpers: There are often small jumpers near the power pins.
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
Do not ignore the flyback diodes. The HW-130 includes 1N4007 diodes on board, but those are too slow for PWM. Better upgrade: solder 1N5819 Schottky diodes across OUT1-2 and OUT3-4 (cathode to positive supply, anode to output).
The shield utilizes a shift register to control four digital pins for motor direction, while PWM pins control speed. Arduino How to use Motor Shield Driver with Arduino UNO
