It s a very simple circuit i used the l293d ic that is a dual bridge motor driver ic.
Motor driver circuit arduino.
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.
Arduino motor control setup.
If you want to learn the basics of l293d ic below tutorial is invaluable.
Connect en1 of ic to pin 2 of arduino.
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.
In the arduino dc motor control using l298n project we will control both the functionalities of a simple dc motor i e.
We will divide this chapter into three parts just make your motor spin.
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.
You will need the following components 1x arduino.
One of the easiest and inexpensive way to control stepper motors is to interface l293d motor driver ic with arduino.
The l293d is a typical motor driver which can drive 2 dc.
While using this shield 6 analog pins which can be used as digital pins too pin 2 and pin 13 of arduino are free.
It can control both speed and spinning direction of any unipolar stepper motor like 28byj 48 or bipolar stepper motor like nema 17.
Warning do not drive the motor directly from arduino board pins.
You can connect two dc motors having voltages between 5 to 35v to these terminals.
The story of this motor shield is that i wanted to make a robot for my multifunctional brainwave controlled system and i decided to share this with you.
The l298n motor driver s output channels for the motor a and b are broken out to the edge of the module with two 3 5mm pitch screw terminals.
Connect in2 of the ic to pin 9 of arduino.
