PSoC 4 Pioneer Kit Community Project#029 – Bluetooth Home Automation System

cy.wbz

Hello!

 

We are continuing with our wireless subseries with the 100 projects in 100 days. Last week we showcased a number of examples using the XBee wireless modules. Yesterday we gave you an example on how to connect your Pioneer kit to a WiFi network. Today we will showcase how to interface with your Pioneer kit using Bluetooth.

 

Today’s project is designed to control the On/Off status of an appliance using Bluetooth. The user is required to have an Android Phone with Bluetooth capabilities through which one can send commands using the Bluetooth SPP Application. This App sends the command to the Bluetooth Shield on PSoC4 which then controls the relays on the Relay Shield. The appliance then turns on or off according to the relay position.

At the bottom of this post we are including the following items:

  • Example Project Zip File
  • Zip File of Images
  • Project Schematic
  • Component Configurations

 

Components Used:

 

The user can download the example project at the bottom of this post. The project uses the following list of Creator Components:

  • UART
  • CyClock
  • Interrupt
  • Logic Low ‘0’
  • CyPin

 

The components are configured by right clicking on the component in your Top Design schematic view and selecting Configure. Please enable the following selections in the Configuration windows for the listed components above.

 

Firmware Description:

 

The main.c firmware is included in the example project. Please review the commented sections for more details.

 

If you need any additional information on the shields that we are using today please take a moment to review the following web pages:

 

This example also uses the Bluetooth SPP app for Android phones. This app is available for Android phones only, and can be found at the following link:

 

Once the user has configured the Bluetooth connection they will be able to use the Bluetooth SSP application to control the Pioneer kit. In the header section of the main.c file you see the defined commands that can be sent to the Pioneer kit. These are the values that the user can enter into the SPP application to either turn on or off the appliance (Light). This example supports up to four applications being controlled from a cell phone.

 

Hardware Connections:

 

For this example you will need to have both the Relay and Bluetooth Shields. We will first insert the Bluetooth Shield into the Pioneer kit. On the top of the Bluetooth Shield are headers that will allow us to then insert the Relay Shield. Here we’ve ‘stacked’ the Arduino shields allowing us to use both the Bluetooth and Relay capabilities.

 

Now that the shield boards are connected to the Pioneer kit we then need to connect the Relay shield to the power supply and then to our light bulb setup. 

 

 

Test Your Project:

 

Program the Pioneer kit, start the SPP application and then begin to send command controls to the Pioneer kit using the pre-defined values.

 

I hope this example can help you in your design.

 

Best,

Matt

  • Will you sell me your system and Android Source code?

    I am in a bit of a hurry,

     

    I simply want to turn on a relay using an Android smartphone.

     

    I have an android app, so I would integrate your code into mine.

     

    Let me know.

    This could be your 101 project in 100 days ;-)

     

    We are building a speed limit aware cruise control for a charity.

    Hi James,

     

    Nice to hear about your cruise control project for charity.

     

    The system (hardware + firmware) source has already been posted above. Its all contained in the PSoC Creator project "Home_Automation_Bluetooth_Relay_Shield.zip (2.5 MB)"


    You will need the $25 PSoC 4 Pioneer Kit, the bluetooth and relay sheilds posted above, and a free download of PSoC Creator to get started.

     

    We didn't write an android app for it, instead used the free Bluetooth SPP app, that allows you to send serial commands from your android phone to the bluetooth shield.

    If you can add a layer of serial communication to your existing android app, you should be able to communicate with the PSoC very easily (using UART)!

     

    We'd love to feature your finished project here when its done!

     

    regards,

    -Gagan

    Unfortunately, I don't have the time to do all that.

     

    Is there anyone on this forum that could assist?

     

    We can publish it all here if you want. I just have to deliver.

     

    Let me know.
