The first two lines of code assign the in1 variable to Arudino pin 10, and the in2 variable to pin 11. Once you’ve built the circuit above, upload this code to your Arduino: int in1 = 10 Here, we’re using a 12V supply to power the motor, and a separate 5V supply to power the Arduino and L293D. You will probably need a separate power supply for the motor. To build this project, connect the DC motor, L293D, and Arduino like this: You’ll learn basic to advanced Arduino programming and circuit building techniques that will prepare you to build any project. If you want to learn more about the Arduino, check out our Ultimate Guide to the Arduino video course. Let’s build an example project that will make a DC motor spin in one direction for two seconds, stop, then spin in the opposite direction for two seconds. To build the example projects, you’ll need the following parts:Ĭonnect the DC Motor and L293D to the Arduino

ARDUINO PROJECT FORWARD AND REVERSE MOTOR USING HOW TO

In this tutorial, we’re going to build a few example projects to demonstrate how to use the L293D to control DC motors on the Arduino. To turn the motor OFF, send a LOW signal to the input 2 pin. To make the motor spin in the opposite direction, send a LOW signal to the input 1 pin, and a HIGH signal to the input 2 pin. This will cause the motor to spin in one direction. To turn the H-bridge 1 motor ON, send a HIGH signal to the input 1 pin, and LOW signal to the input 2 pin. Input 4: motor control signal for H-bridge 2.Input 3: motor control signal for H-bridge 2.Input 2: motor control signal for H-bridge 1.

Input 1: motor control signal for H-bridge 1.

Enable 3, 4: turns ON/OFF H-bridge 2 (HIGH enables, LOW disables).

Enable 1, 2: turns ON/OFF H-bridge 1 (HIGH enables, LOW disables).

Vcc 2: power supply for the motors (4.5V to 36V DC).

Ive also tried just attaching the base to a dc regulated power supply instead of the Arduino’s set 5V and slowly increasing the voltage until it lets enough current through that the motor runs which ive found the transistor can do with only about 1.5 volts but even then the transistor gets incredibly hot within a few seconds, Ive also made sure to clear any code on the arduino that could somehow cause this.H-bridge 1 can control one motor, and H-bridge 2 can control another motor. Ive tried multiple things increasing the size of the resistor in between the 5V output and the base from 1k to 10k which slows down the overheating but only for a couple of seconds and also doesn’t gain a response from the motor as consistently. Im having an issue with the circuitry on Figure 4-3, I’ve wired it up exactly the way the book says as well as a few different configurations which all amount to the same thing, and it works in terms of the motor runs when its in the 5V pin which is where the book says to test before moving on but as soon as voltage is applied to the base of the transistor allowing current flow from the 9V battery the transistor gets incredibly hot within a couple secs, in fact before I even realized it was doing that I burnt one out.

So don’t forget to submit your project. If you want to learn more about analog input filtering in software, check out this example code. If you want to wire that up, take a look through this Wikipedia article, and read through this tutorial. I mention in the video that you can control DC motor direction using an H-Bridge. We’ll control the servo using a PWM signal from the arduino, and I’ll show you how you can turn analog distance readings into precise angles for the servo to turn to! Next, it’s onto 180 degree servo motors, which we will power on an independent 5V rail using a voltage regulator. This week, we’ll finally be using the Arduino to control some motors! First up, we’ll control a standard DC motor running off a 9V battery with the help of an NPN transistor and a PWM (Pulse Width Modulated) signal from the Arduino.
