When you’re done you should have something that looks similar to the illustration shown below. You can interchange your motor’s connections, technically, there is no right or wrong way. Note that the Arduino output pins 9 and 3 are both PWM-enabled.įinally, connect one motor to across OUT1 & OUT2 and the other motor across OUT3 & OUT4. Now, the input and enable pins(ENA, IN1, IN2, IN3, IN4 and ENB) of the L293D IC are connected to six Arduino digital output pins(9, 8, 7, 5, 4 and 3). Make sure you common all the grounds in the circuit. Connect Vcc1 pin to 5V output on Arduino. Next, we need to supply 5 Volts for the L293D’s logic circuitry. So, we will connect external 9V power supply to the Vcc2 pin. In our experiment we are using DC Gearbox Motors(also known as ‘TT’ motors) that are usually found in two-wheel-drive robots. Start by connecting power supply to the motors. Now that we know everything about the IC, we can begin hooking it up to our Arduino!

Wiring L293D motor driver IC with Arduino UNO But, with Pulse Width Modulation (PWM), we can actually control the speed of the motors. Pulling these pins HIGH will make the motors spin, pulling it LOW will make them stop. ENA and ENB are used to turn ON, OFF and control speed of motor A and motor B respectively. I’ve moved a copy of the L298N truth table below, for your reference. Typically the manufacturer will include a truth table outlining key functionality. First, we will take a look at the L298N Motor Controller Specifications.

The higher the duty cycle, the greater the average voltage being applied to the dc motor(High Speed) and the lower the duty cycle, the less the average voltage being applied to the dc motor(Low Speed).īelow image illustrates PWM technique with various duty cycles and average voltages. For this tutorial, I’m going to show you how to translate motor controller specifications into the Arduino code. The average voltage is proportional to the width of the pulses known as Duty Cycle.

PWM is a technique where average value of the input voltage is adjusted by sending a series of ON-OFF pulses. A common technique for doing this is to use PWM (Pulse Width Modulation) The speed of a DC motor can be controlled by varying its input voltage. H-Bridge – For controlling rotation direction.

This can be achieved by combining these two techniques. Learn about L298N Motor Driver module along with PWM, H-bridge Working, Pinout, Wiring, Arduino Code for controlling speed & direction of DC motor. In order to have a complete control over DC motor, we have to control its speed and rotation direction. these loops so the values soon go out of the allowed range of 0 to 180.Ī.write(++pos4) // After each time through this loop pos4 will be 90, then 180, then 270.ī.write(-pos3) // After each time through this loop pos3 will be 90, then 0, then -90.One of the easiest and inexpensive way to control stepper motors is to interface L293D Motor Driver IC with Arduino. WARNING! The global variables pos3 and pos4 are not being re-initialized before

Just add 90 to all your positions: #include I wrote the code but I don’t get what I am doing wrong. I am trying to control the position of 2 servo motors (Servo A and Servo B) using l298n on proteus to see the signal waveform on the virtual oscilloscope.
