Instructions to setup

Hardware and Source Code

• Make the Circuit Connections as per the Circuit Diagram.
• Create a new Tiva TM4C123GH6PM Project in Keil μVision-5.
• Select the following checkboxes in the Manage Run-Time Environment Window.

• Copy the source code file main.c to your Keil Project under Target > Source Group.
• Build the project (F7) and Set the Options for Target as follows

• Download the code into the Microcontroller's Flash Memory (F8) and press the Reset button on the Microcontroller to run the code.

Interacting with the Hardware Using Bluetooth

• Install the Serial Bluetooth Terminal App from Play Store on your Mobile Device.
• After that turn on Bluetooth of your smartphone or Android based mobile and scan for available Bluetooth devices. You will see the HC-05 device in your scanned list. The default name for this Bluetooth device is “HC-05” and the default pin code is either “0000” or “1234”.
• Now open your serial Bluetooth terminal Android application and click on menu->devices. You will find the list of available nearby Bluetooth devices.
• Select HC-05 and the serial Bluetooth terminal starts to pair with HC-05. It will ask for the pin code and enter the pin code mentioned above.
• After pairing, it will show a successful connection message.
• 1. Now Type 'T' and click on the send button to get the current temperature recorded by the device.
  2. Type 'H' and click on the send button to get the current humidity recorded by the device.
