For this first project, we are only going to use the HM-10 Bluetooth module and the Arduino. You will need to connect the Bluetooth module to the Arduino as shown in the previous circuit diagram. The following diagram shows this:
Now we need to write the code to access the Bluetooth module. We will be using the SoftwareSerial library to interface with the HM-10 Bluetooth LE module. This library was developed to allow serial communication on digital pins other than pins 0 and 1. There may be limitations to this library if you are using a board other than the Uno. You can reference the documentation (https://www.arduino.cc/en/Reference/softwareSerial ...
