In this video, you will learn how to control the speed and rotation of a DC motor using L293D, which is a motor driver IC. It is a low voltage operating device like other ICs. The reason to use it is that the Arduino can only provide output of 5V. The main thing to be noted is that the DC motor should be powered only through a power supply or a suitable battery bank and don’t connect the module directly to the raspberry Pi. It can actually control one motor independently. So we need intermediate circuits to connect the controller to the motor, called drivers. It has 16 pins and it can control two DC motors at a time. L293D Like This is a very useful chip. Controlling a DC Motor. It's super simple! Arduino board of your choice; Micro USB cable; L293D motor driver; DC motor Drive the DC Motor by L293D Chip. This IC is powerful enough to control DC motor with low current. If you are planning on assembling your new robot friend, you will eventually want to learn about controlling DC motors. In both ICs, drivers are enabled in pairs, with drivers 1 and 2 are enabled by a high input to 1,2EN and drivers 3 and 4 are enabled by a high input to 3,4EN. This puts the two chips in parallel mode so the voltage will remain the same as before but the current increases. One of the easiest and inexpensive way to control DC motors is to interface L298N Motor Driver with Arduino. Arduino boards are available as pre-assembled boards and we can use their software to program it. L293D is suitable for small current drawing motors like BO motor, DC geared motors up to 500 RPM, and small stepper motors which take less current up to 600mA at their highest torque rating. As L293D IC has two H-Bridges, each H-Bridge will drive one of the electromagnetic coils of a stepper motor. My final goal is to use an arduino nano with my homebuilt L293 chip. What i am struggling with i a code and the Connections to it. As the name suggests it is mainly used to drive motors. Lets control an DC motor with a L293D chip and make it so it will go clockwise or counter clockwise. Connection. Drive a DC motor forward and in reverse with variable speed. Before we start the wiring. By Simon Monk. Before using the L293D motor driver shield with Arduino IDE, you need to install the AFMotor library. L293D Motor Driver IC . Also, you should be using an L293D Motor Driver IC in order to control the direction of motor’s rotation. I have a external 12v power supply that i want to use for the Motor (12v-18v) and also the Tactile push button that i want to use so that when the button is pushed, the Screen comes up out of the Table.

The L293D is a popular 16-Pin Motor Driver IC. This L293D shield is most commonly used for Arduino Uno, but figured if I looked at the pin layouts of the Uno and the Nano and wire appropriately it would be fine. We have connected both of these to the Arduino 5V pin. So the entire thought is to solder another L293D chip straightforwardly over the present one. L293D is a 16-pin IC which can control a set of two DC motors simultaneously in any direction. Step 1: L293D DC Motor Driver & Pin Configuration “The L293D is a monolithic integrated, high voltage, high current, 4-channel driver.” Basically this means using this chip you can use DC motors and power supplies of up to 36 Volts, thats some pretty big motors and the chip can supply a maximum current of 600mA per channel, the L293D chip is also what’s known as a type of H-Bridge. The other ICs could have the same functions like L293d but they cannot provide the high voltage to the motor. After above operations are completed, connect the Arduino board to your computer using the USB cable. These diodes protect our circuit from the Back EMF of DC Motor. WhereasL298N has the advantage of higher output current up to 2A and therefore it is suitable for high torque and high RPM motors like Johnson motors and high torque DC Geared motors. However, if you were using a more powerful motor, or a higher voltage motor, you would provide the motor with a separate power supply using pin 8 connected to the positive power supply and the ground of the … In order to use an L293D motor driver board you must first understand the fundamentals of how the IC works.
