1. H-Bridge L293D – Motor Driver

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.

2. Bluetooth Module

HC-05 or 06 chip of Bluetooth module solderes to the module board containing DC-DC converter and level conversion RX and TX signals.

Chip HC-05 needs power of 3.3V, but thanks to the converters, you can connect this module to the boards power by 5V.

3. RemoteXY

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