BlueCArd - How to connect a Bluetooth BLE module (AT-09 or HM 10) to Arduino Nano - ep. 6

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. Find more info and cool stuff in my blog: 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 l
