Shield For Arduino Datasheet Free 2021 | Hw 130 Motor Control

to expand 3 Arduino pins into 8 control lines for the H-bridges. Direction Control

: One 74HC595 8-bit shift register used to control motor directions. Input Voltage : 4.5V to 25V DC (Motor supply). hw 130 motor control shield for arduino datasheet free

const int motorPin = 9; // motor pin

: Remove the power jumper to separate logic and motor power. Power the Arduino via USB or the DC jack. Connect the motor supply to the EXT_PWR terminal block. to expand 3 Arduino pins into 8 control

This is the critical part of the . The shield does not use the same pins as the standard Adafruit motor shield. Here is the exact mapping: const int motorPin = 9; // motor pin

⚠️ The HW 130 does not use D3 for PWM like the official L293D shield. Check your pinout.

: With the power jumper (PWR) installed, the Arduino and motors share the same power source (either the DC jack or the EXT_PWR block).
