So if you are planning to use more than 12 volts to power the motors, remove the jumper. The L298N can be powered from 5V to 35V (depending on the specification).īut it is important to note that if you power it with more than 12 volts the onboard 5V voltage regulator will be damaged. But in case they are missing or not set, you should verify their placement before proceeding. This type of board is usually shipped with three jumpers already in place. These instructions are based on the silkscreen of the board that I have.

But it reduces the chance of shorting if you place the board on metal or spill something on to the work surface. Make sure the wheels aren't touching the supporting wheel.Make sure that the wires are closer to the middle.Use the standoffs to hold the two motors together.If you have a 3D printer, clamp, helping hands or some spare parts you can design something a bit more stable. This is a quick way of putting together a rig that won't roll away while testing. You can buy the parts for this article by following my affiliate links to either Amazon or AliExpress: Part
#L298N MOTOR DRIVER NOT WORKING HOW TO#
I'll provide a quick demo program so you can see how to run the motors through a predefined sequence. In the second part I will show you how to quickly wire up the driver to an Arduino. It should also give you ideas for very simple robot projects. This will give you a better understanding of how a motor driver works. In the first part I will show you how to control the driver without the need for a computer. Most motorized toys and many robot chassis kits use simple DC motors. When you’re done you should have something that looks similar to the illustration shown below.In this tutorial I cover how to drive two DC (direct current) motors using an L298N motor driver.

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. 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. 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. In order to have a complete control over DC motor, we have to control its speed and rotation direction. One of the easiest and inexpensive way to control stepper motors is to interface L293D Motor Driver IC with Arduino.
