For this first define CUSTOM_SETTINGS followed by defining INCLUDE_modulename. You can reduce the size of library compiled by enabling only those modules that you want They can turn pin ON or OFF, canĪlso vary its PWM if that functionality is supported on that pin.ġ)For Arduino Mega Connect Bluetooth on Serial3 pins.Ģ)For Arduino Uno/Nano library uses SoftwareSerial,hence pin 2 and pin 3 are usedĪs RX and TX pins respectively on SoftwareSerial.Hence with arduino Unoģ)For Uno/Nano keep bluetooth Baudrate below 38400. Led Brightness Control Module allows user to control any digital pin on their board. You can enter the pin value as 13 in the Dabble app since there is an in-built led present on evive at pin 13. Serial.println(LedControl.readBrightness()) Serial.print("State:") //0 if led is Off. evive #define CUSTOM_SETTINGSĭabble.begin(115200) //Enter baudrate of your bluetooth.Connect bluetooth on Bluetooth port present on evive. Either copy the codes given below as per your selected board or you can also navigate to “Files>Examples>Dabble>” and select the Led Brightness Control example as per your board. Here in this example, we are controlling the LED brightness and also displaying the pin number, state, and brightness of the LED on the serial monitor. To set the baud rate you have to use set bluetooth baud rate to () block.Įxamples Arduino IDE Example for LED Brightness Control Module Note: When you are using this module with Arduino Uno, Mega, and Nano, you have to set the Bluetooth baud rate to the baud rate of the Bluetooth module to have proper communication between the board and the module. Its function is to enable the LED Brightness Control feature of Dabble. There is a stacked block named “ enable LED control ” available for this module. It returns int data type with a value ranging between 0 and 100. LedControl.readBrightness(): This function returns the brightness value set by the user in the mobile app.This function returns the following output: LedControl.getpinState(): The function returns the state of the pin set by the user in the mobile app.LedControl.getpinNumber(): This function returns the pin selected for LED Brightness control in the mobile app.If you want to get the pin number, its state, and brightness value of the LED from the module, then these are the functions using which you can do that: This function also changes the state and the brightness of the LED automatically and you don’t have to do anything. To refresh the data that the device has got from the mobile app, you have to use the following line of code: The default name given in the library is “MyEsp32”. With evive, you normally get 115200 baud rate modules.ĭabble.begin("Bluetooth_Name") In place of Bluetooth_Name enter the name that you want to keep for Bluetooth of ESP32. For evive and Arduino Mega, Uno, and Nano:ĭabble.begin(Baud_Rate) Here Baud_Rate is the baud rate set for the Bluetooth module.To enable Bluetooth communication, you have to initialize serial communication using the following code: evive, Uno, Mega, and Nano – Dabble-Arduino.You can download the zip of Arduino Library for depending on the board you are using. To include the LED Control module in the Arduino program, you have to include the following header: #define CUSTOM_SETTINGSĪfter defining the above mention headers, you have to include the dabble library: Digital pins with no brightness control: digital pins 14-43 and 47-53.Digital pins with no brightness control: digital pins 2,4,7,8,12 and 13.Digital pins with no brightness control: digital pins 21-26.You can choose the following pins for the corresponding boards: To change the pin, you can click on the button showing the Pin (In the above image it is Pin: 13 button). The module is made for activities like controlling LEDs. Knob range is from 0 to 100 and it is mapped to PWM values. Potentiometer type knob as seen in the image is used for controlling PWM. If the digital pin is a PWM pin then you can also vary PWM of that pin in order to get different output voltage at that pin.LED Brightness module controlling Digital Pin13. LED Brightness module controlling digital pin 13. If the pin is a digital pin with no PWM support, then you can control the HIGH and LOW state of the pin by clicking on the ON/OFF icon present in the center of the module.This module allows you to control the output of the digital pins in two ways: The LED Brightness Control is the first module of the Dabble App.
