![]() ![]() IoT Builder removes the necessity for the user to know about HTML, JavaScript, Python and the TCP/IP interconnect. All of the complexity of the transport layer and the communication between the hardware and the remote front panel is abstracted from the users program, leaving the programmer to implement desired functionality. ![]() The front panel is drawn in the panel editor and the logic for the user interface is programmed at a high level with either flowchart blocks or Arduino C / Raspberry Pi Python method calls. IoT builder is therefore well suited both for teaching the principles of IoT based applications to beginners and also as a rapid prototyping tool for more experienced developers. The firmware program is where we need to interact with both the hardware peripherals of our appliance and the IoT controls on our remote front panel. Since both the appliance and the front panel are designed in Proteus, IoT Builder is able to make life much easier during programming.įor example, a button press on the front panel may turn on an LED in the appliance, but equally sensor data from the appliance may update a display on the front panel. The project tree contains a list of the peripherals you have added and also a list of the IoT controls in your front panel. Each of these expands to show you high level function calls that allow you to control them. For example, a display control will have a print() method and a temperature sensor will have a readTemp() method. So, you just have completed the RGB remote control experiment.You can then drag and drop these method calls directly from the project tree into your program. While in PLAY mode, you won’t be able to drag or set up new widgets, press STOP and get back to EDIT mode.Īt the same time, you can see the hardware side as below: This will switch you from EDIT mode to PLAY mode where you can interact with the hardware. (D – stands for Digital).Īfter you finished all above operations, open the Serial Monitor, then open the Blynk APP, press the PLAY button. Here we connect the RGB Pin R to D11, Pin G to D12,Pin B to D13. The list of pins reflects physical pins defined by your hardware. The most important parameter to set is PIN . Widget Settings – Each Widget has it’s own settings. Now pick a zeRGBa.ĭrag-n-Drop – Tap and hold the Widget to drag it to the new position. ![]() All the available widgets are located here. Tap anywhere on the canvas to open the widget box. Your project canvas is empty, let’s add a zeRGBa to control our RGB module. Wait until you see something like this:Ĭongrats! You are all set! Now your hardware is connected to the Blynk Cloud! Add a Widget Please check your email and copy it, then paste it inside the quotation marks.Ĭhar auth = “f45626c103a94983b469637978b0c78a” This is the Auth Token that you emailed yourself. Check other examples on how to communicate with Blynk. You can inject your own code or combine it with other sketches. Go to the Project Settings (nut icon). You should get Auth Token in the Blynk App. ![]() Then load up the following sketch onto your Arduino. Code ProgramĪfter above operations are completed, make sure that the Yun Shield is on the same network with the computer. Open the Arduino IDE and choose corresponding board type and port type for you project. Here we connect the RGB Pin R to D11, Pin G to D12,Pin B to D13,GND to GND.
