Step 2: H-Bridge L293D

L293D is IC which is commonly used as a H-bridge.

There are also other IC’s like L298 etc. but in this tutorial, we will see how we can use L293D. At the same time, you can use Motor driver chip L298N in this project.

Step 3: Connection

HC-06 chip of Bluetooth module solderes to the module board containing DC-DC converter and level conversion RX and TX signals.

Chip HC-06 needs power of 3.3V, but thanks to the converters, you can connect this module to the boards power by 5V.

Step 4: Application

RemoteXY is easy way to make and use a mobile graphical user interface for controller boards to control via smartphone or tablet.

Step 5: Code

You can use these codes in both L293D and L298N.

I will share the added codes as a single section. So watch carefully where to add the code blocks I've added!
