![]() ![]() ![]() 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”. In place of Bluetooth_Name enter name that you want to keep for Bluetooth of ESP32. With evive, you normally get 115200 baud rate modules. Here Baud_Rate is the baud rate set for the Bluetooth module. For evive and Arduino Mega, Uno and Nano. ![]() To enable Bluetooth communication, you have to initialize serial communication using the following code: evive, Uno, Mega, and Nano – Dabble-Arduinoĭepending on the board you are using.You can download the zip of Arduino Library for To include the LED Control module in the Arduino program, you have to include the following header:Īfter 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. ![]()
