We will be able to connect four DC motors rated at 4.5-25 V at these terminals. At both the left and right sides you can view five pin terminals. You will be able to connect two servo motors at these terminals as a single servo motor comes with three wires that need to be connected. At the top left corner you can view two three pin headers. Two servo motors, Four DC Motors and Two stepper motor connections can be found on this motor driver shield. The figure below shows all the motor connections present in the L293D Motor Driver Shield.
Arduino lcd library shift register serial#
Using serial in parallel out protocol, it obtains data serially from the Arduino board and transmits it through the parallel pins. The shift register controls several outputs simultaneously. We can use shift registers such as 74HC595 to save microcontrollers pins. The 74HC595 is a serial-in and parallel-out shift register IC.

So as the motor driver shield consists of two L293D ICs hence 4 DC motors or 2 stepper motors can easily be controlled by this driver.įor more information about L293D IC we have a dedicated tutorial related to it: L293D Motor Driver IC introduction, pinouts and how to use L293D has an internal H-bridge installed that can operate two DC motors or a single stepper motor. The Polarity of current can change at any time without affecting the whole IC or any other device in the circuit. L293D provides a continuous bidirectional Direct Current to the Motor.

It is a low voltage operating device like other ICs. The L293D motor driver shield features two L293D motor driver ICs and one eight-bit shift register chip. L293D Motor Driver Shield’s Integrated Circuit Let us see what makes this motor driver shield such a suitable option. L293D motor driver shield is a great option to drive several motors using Arduino and used in projects such as four-wheeled robots, CNC machines, and printers. Demonstration L293D Motor Driver Shield.
