This tutorial is part of the tutorials how to build BlueCArd - a simple (and cheap) to build Arduino Nano RC car controlled from Android mobile device through Bluetooth.

In the previous tutorial I shoed You hot to power the Arduno Nano with a DC DC Boost converter. If you haven't watched the video yet, you can find it here:

In this tutorial I'll show you how to connect and wire a Bluetooth Low Energy module to the Arduino Nano microcontroller on a breadboard. I'll show You then how to write a sketch to test the connection and how to configure the Bluetooth module.

For the BlueCArd project I used an AT-09 BLE module which is fully compatible with the HM-10 BLE module. BLE is very convenient for this project, because it doesn't need pairing of the devices and is relatively easy to use.

I also wrote a blogpost, where I explain in detail how exactly to connect the Bluetooth module and how to lower the voltage for the RXD pin using a voltage divider with two resistors. You can find this post on my blog here:

This video is part of the BlueCArd tutorials with an ultimate goal to build the BlueCArd. You can watch the BlueCArd in action in this video:

BlueCArd is an easy to make fully 3D printed (I printed it on my Prusa i3 MK3s 3D printer) Arduino based Bluetooth controlled (from Android phone) RC car.
