One of its main advantages is that it can control the speed and direction of two DC motors independently. In this project we will learn how to decode IR remote signals with Arduino and to control DC motors depending on the button pressed. Run the program and open the Serial Port at the top right of the Arduino software. Now in the main program the following section will decode the received IR signal and will be stored in the variable named ‘value’. Now, in void loop (), we are reading the analog value (from A0) using analogRead(pot), and saving it to variable c2. The rotary encoder push button terminal is connected to the Arduino pin 4, with this button we can change the direction of rotation of the motor. We are using L293D motor driver IC to drive motor since Arduino won’t be able to supply enough current to drive a DC motor. #define button 4 10. I have tried to recieve a signal from two different TV remotes on the “Finding IR remote code” and no remote codes are printed to the console window. To control the direction of the spin of DC motor, without interchanging the leads, you can use a circuit called an H-Bridge.An H-bridge is an electronic circuit that can drive the motor in both directions. In the next section we are defining all digital input output pins of Arduino which are used in this project. Code for controlling a DC motor. Now let’s make some practical applications. Connect first DC motor to Pin 3 and Pin 6 of L293D. The MotorControl sketch To gain control of the speed of your motor whenever you need it, you need to add a potentiometer to your circuit. You can use the MotorControl sketch for the Arduino to put some input into a DC motor to give you full control of the motor on the fly. In this project we will learn how to decode IR remote signals with Arduino and to control DC motors depending on the button pressed. To control the direction of the motor, the pins in1 and in2 must be set to opposite values. Now we can connect L293D IC to Arduino Uno. " Arduino Speed/Direction control with 4 DC Motors and 2 Pots, need help "Hi everyone, I need some knowledge of yours. Recommended Readings: So we need an L298N driver, a DC motor, a potentiometer, a push button and an Arduino board. Coming to the project code portion.

Using Sensor to control the Direction and Speed of DC Motors. 1. i tried same connections but my aurdino is not getting on. The rotary encoder has 5 pins: GND, + (+5V or 3.3V), SW (push button), DT (pin B) and CLK (pin A). When I try to compile the “Finding IR remote code” program I get this error message. https://core-electronics.com.au/tutorials/dc-motors-with-arduino.html In this article and it’s accompanying video I’ll show you everything you need to know to start adding some motion to your next Arduino project. Using Sensor to control the Direction and Speed of DC Motors. Pin IN1 and pin IN2 are the control pins where: Arduino pin 5 and pin 6 are PWM signal outputs, at any time there is only 1 active PWM, this allows us to control the direction as well as the speed by varying the duty cycle of the active PWM signal. Arduino DC motor speed and direction control with L293D This example shows how to control a DC motor speed and direction of rotation using Arduino UNO and L293D motor driver chip. With the Arduino Uno Board you will be able to control the H-Bridge quite easily. And as a bonus, it can even control a unipolar stepper motor like 28BYJ-48 or Bipolar stepper motor like NEMA 17.
