Motor Driver Circuit Arduino

We will divide this chapter into three parts just make your motor spin.
Motor driver circuit arduino. 1 motor driver circuit for arduino. While using this shield 6 analog pins which can be used as digital pins too pin 2 and pin 13 of arduino are free. The h bridge is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output e g. This may damage the board.
It s a very simple circuit i used the l293d ic that is a dual bridge motor driver ic. Connect en1 of ic to pin 2 of arduino. Connect in2 of the ic to pin 9 of arduino. L293d motor driver arduino interfacing.
Connect sens a pin of ic to the ground. It can control both speed and spinning direction of any unipolar stepper motor like 28byj 48 or bipolar stepper motor like nema 17. Arduino motor control setup. How to use the l293d motor driver with arduino.
The l293d is a typical motor driver which can drive 2 dc. Speed and direction of rotation using a combination of pwm signal and l298n h bridge. Control the direction of the spin of dc motor. You will need the following components 1x arduino.
Each channel on the module can deliver up to 2a to the dc motor. Warning do not drive the motor directly from arduino board pins. What is a motor driver a motor driver is a small current amplifier whose function is to take a low current control signal and then turn it into a higher current signal that can drive a motor. One of the easiest and inexpensive way to control stepper motors is to interface l293d motor driver ic with arduino.
If you want to learn the basics of l293d ic below tutorial is invaluable. The shield contains two l293d motor drivers and one 74hc595 shift register. In the case of using servo motor pins 9 10 2 are in use. Connect 5v and ground of the ic to 5v and ground of arduino.
You can connect two dc motors having voltages between 5 to 35v to these terminals. L293d motor driver modules usually come with an inbuilt lm317 voltage regulator circuit or similar voltage regulating circuit along with connectors. How to use arduino l293d motor driver shield. Connect in1 of the ic to pin 8 of arduino.
Use a driver circuit or an ic. In the arduino dc motor control using l298n project we will control both the functionalities of a simple dc motor i e. Connect the motor to pins 2 and 3 of the ic. Arduino uno l298n motor driver module 12v dc motor 100kω potentiometer.
The shift register expands 3 pins of the arduino to 8 pins to control the direction of the motor drivers.
