This is designed to provide bidirectional drive currents at voltages from 5 V to 36 V. IN3 and IN4 are connected to digital outputs on the Arduino. Driving servos with L293D motor shield is very easy. Arduino Code – Controlling a DC Motor. The L293D is a dedicated module to fit in Arduino UNO R3 Board, and Arduino MEGA, It is actually a motor driver shield that has full featured Arduino Shield can be used to drive 2 to 6 DC motor and 4 wire Stepper motor and it has 2 set of pins to drive a SERVO. You can use it to control small dc motors - toy motors. Connecting Arduino Motor Shield L293D to Raspberry Pi. Lets control an DC motor with a L293D chip and make it so it will go clockwise or counter clockwise. The Arduino Motor Shield Rev3 is built around the L298 dual full-bridge driver, made by STMicroelectronics. To solve this, we should use a motor driver. You can use a generic motor shield as well but the code will change. A Bluetooth shield was connected to the Arduino board. The H-Bridge is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output. L293D is a Motor driver IC used to control motors with a microcontroller. That’s it guys, your layout is now complete. Here is a design for a full-featured motor shield that will be able to power many simple to medium-complexity projects.
