![]() The working of this circuit is very easy.Īrduino Code for Bluetooth Controlled Robot Finally, to power it all up, we are using a 9V battery. Finally, we are using pins 9, 6, 5and 4 to connect the L298N motor driver IC that is driving four of our motors. Next, we are using pins 11,12,8, and 7 to connect our WS2812B RGB leds. ![]() The Bluetooth module is connected to pin 13 and 10 of the Arduino that we are using as the software serial. First, we have the Arduino which is working as the brains of the circuit. The working of this circuit is very simple and easy to understand. This circuit is made out of generic components and can be found in your local store or it's easily available on any online store so the replication process becomes easier. The complete circuit diagram for the Arduino Bluetooth Car is shown below. For the connectivity, I have used Female berstrips, male berstrips, and relimate connector onboard. ![]() Since Arduino Protoshield can be used for direct connection of IN1, IN2, IN3, IN4 of the motor diver, and other connections but I had tried to make my own protoshield for the onboard connections. I have made a separate Hardware attachment for the motor driver that will provide the connections to the Arduino Uno board. Just randomly attach the motors with the driver as the polarity and direction can be controlled using the input pins attached with the Arduino. Since we are using the L298N Module, we have 2 screw terminals on both sides for connecting the motors. Please refer to the video for more information. Tip: If you connect the motor in the corresponding cross direction then it will be connected in parallel. Likewise, Right side motors are connected in parallel drive and same with the left one. Now all four motors will be connected in such a way that they will be formed into two pairs and each pair will be connected in parallel to each other. Rectangular piece of 10.5 X 13.5 cm (2 pcs).Note: I recommend cutting extra pieces of the sunboards so that you can replace them easily if they get broken during the building process. We will require half of the full sheet for our whole construction. These boards are equally strong as cardboards but they are lightweight and cost-effective. So, we will be using sunboards to make a reliable and strong chassis.
