![]() ![]() ![]() In order to do so, connect pin 8 to the external power source's +ve end,ĪKA battery (on my robot, I used 4 AA Batteries = 6V), then connect the -ve end of the power source to the GND on the Arduino (common ground). ![]() You will need: Arduino board of your choice Micro USB cable L293D motor. And pins 10 and 15 should also connect to the digital pins on the Arduino to control Motor B. The L293D is a 16-pin Motor Driver IC which can control up to two DC motors simultaneously, in any direction. Now connect the Pins 2 and 7 to the digital pins on the Arduino, they will used to send commands to Motor A. This gets worse as current needs increase. Lesson 51: Control 2 DC motors using Arduino and L293D Arduino Step by Step Course 827 views 42 Dislike Share Save Robojax 80.4K subscribers In this lesson we learn how to use. Not with dropping 2 volts as a bipolar device (4.5 volts is the minimum motor source voltage anyhow). At Sparkfun and Pololu they have very nice motor drivers with mosfets. Pins 3 and 6 control one motor (motor A) and pins 14 and 11 control the second motor (motor B). At 5V it does not work very well, or not at all. L293D Motor shield with two L293D motor drivers, can drive 4x DC motors or 2x Unipolar or Bipolar Stepper Motors. When this jumper is installed, the power from the Arduino DC power jack is. Connect pins 4, 5, 12 and 13 together then connect them to the GND pin on the Arduino. The L293D quadruple half-H drivers chip allows us to drive 2 motors in both directions, with two PWM outputs from the Arduino we can easily control the speed as well as the direction of rotation of one DC motor. To select this, there is a jumper near the 2 terminal power connector labeled PWR. The next step is to connect the ground pins together. The L293D is a 16-pin Motor Driver IC which can control up to two DC motors simultaneously, in any direction. Start by connecting all the pins that need the 5V from the Arduino, connect pins 1, 16 and 9 together then connect them to the +5V (Vcc) on the Arduino. The first picture shows how the L293D pins are numbered. The pictures are done by me with the help of Firtzing and a photo editor. ![]()
