HOW TO CONNECT L298N MOTOR DRIVER TO SENSOR SHIELD V5 BLUETOOTH

We connect your phone with the BlueTooth module. This Smartphone gives a Bluetooth signal to the car and from the signal, the car works.įor running the car wirelessly we are using the HC-05 Bluetooth module. This Smartphone gives a Bluetooth signal to the car and from the signal, the car works.Ĭomponents used in the Arduino Car project:Īrduino Bluetooth control car is a simple robot car that can be controlled by your smartphone. Arduino Bluetooth control car is a simple robot car that can be controlled by your smartphone.

Today in this article we are going to discuss How to make a Bluetooth Controlled car using Arduino so without wasting any time let’s make the Arduino car. When you’re done you should have something that looks similar to the illustration shown below.Bluetooth Controlled RC car – Arduino Program: 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 terminal A(OUT1 & OUT2) and the other motor to terminal B(OUT3 & OUT4). Now, the input and enable pins(ENA, IN1, IN2, IN3, IN4 and ENB) of the L298N module are connected to six Arduino digital output pins(9, 8, 7, 5, 4 and 3). We will make use of the on-board 5V regulator and derive the 5 volts from the motor power supply so, keep the 5V-EN jumper in place. Next, we need to supply 5 Volts for the L298N’s logic circuitry. Considering internal voltage drop of L298N IC, the motors will receive 10V and will spin at slightly lower RPM. So, we will connect external 12V power supply to the VCC terminal. 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 module, we can begin hooking it up to our Arduino! Wiring L298N motor driver module with Arduino UNO OUT3 & OUT4 pins are connected to Motor B. OUT1 & OUT2 pins are connected to Motor A. Removing the jumper and connecting this pin to PWM input will let us control the speed of Motor B. Pulling this pin HIGH(Keeping the jumper in place) will make the Motor B spin, pulling it LOW will make the motor stop. If both the inputs are either HIGH or LOW the Motor B will stop.ĮNB pins are used to control speed of Motor B. When one of them is HIGH and other is LOW, the Motor B will spin. IN3 & IN4 pins are used to control spinning direction of Motor B. If both the inputs are either HIGH or LOW the Motor A will stop. When one of them is HIGH and other is LOW, the Motor A will spin. IN1 & IN2 pins are used to control spinning direction of Motor A. Removing the jumper and connecting this pin to PWM input will let us control the speed of Motor A. Pulling this pin HIGH(Keeping the jumper in place) will make the Motor A spin, pulling it LOW will make the motor stop. If the 5V-EN jumper is removed, you need to connect it to the 5V pin on Arduino.ĮNA pins are used to control speed of Motor A. If the 5V-EN jumper is in place, this pin acts as an output and can be used to power up your Arduino. Remember, if the 5V-EN jumper is in place, you need to supply 2 extra volts than motor’s actual voltage requirement, in order to get maximum speed out of your motor.ĥV pin supplies power for the switching logic circuitry inside L298N IC. 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 andaverage 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.

One of the easiest and inexpensive way to control stepper motors is to interface L298N Motor Driver with Arduino.
