How to make a Bluetooth control 4WD car
Hello guys, Welcome back to my SriTu Hobby blog. Today we are going to talk about how to make a Bluetooth control 4WD car. For this, we mainly need Bluetooth technology. Today we are using a Bluetooth module for our project. You can control this car through your smartphone. For that, we need a small app. We’ll talk about that later. What is Bluetooth? How does it work? I have given you a complete description of this in a previous article. If you want you can read that article from this link. Read me.
Next, we need the power to move this car. For this, I am using 4 gear motors. This is why we can call this car a 4WD (Four-wheel) car. The next question we have is how to control these four gear motors through an Arduino board. Of course, we can’t do this directly through the Arduino board. For this, we need the help of another device. That means we need a motor driver board. If you do not know what a motor driver board is, click on this link. Read me.
Now let’s see what other components are needed to create this smart car.
If the Bluetooth module is connected correctly, the circle on the left will be green. Right now click the arrow buttons. Then look at the smart car movement. The full video guide is given below. We will meet in the next article.
