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) to see if your board has any limitations.
The code will need to start off by including the SoftwareSerial header file and then initiate an instance of the SoftwareSerial type. We also want...
