TX of HC05 to Digital Pin 2 of Arduino Uno.You have to connect the HC05 Bluetooth module to Arduino Uno in the following way: You have to connect the HC05 Bluetooth module to evive’ Bluetooth headers in the following way: Choose the board with which you want to set up your Dabble app.ĭiagrams mainly show setup with HC-05 however same pin connection setup goes for HM-10 and HC-06. The first and foremost thing is connecting the Bluetooth module to the development board.Ī circuit diagram for connecting the Bluetooth module with different boards is given below. Hence, if you are using HM-10, then make sure it is the original one. They may or may not perform properly with the app. Note: There are various clone modules available for HM-10. ESP32-WROOM-32, ESP32-WROVER, ESP32-DevKitC or any development board based on Espressif ESP32 will work with Dabble. It is a low-power system on a chip microcontroller with dual-mode Bluetooth and integrated Wi-Fi. Due to the low energy protocol data transfer rate on HM-10 is slower compared to HC-05 and HC-06. It differs from HC-05 in terms of a few hardware configurations and a fact that it can only be used as a slave. This is also a Serial Bluetooth module with Bluetooth protocol "Bluetooth V2.0+EDR". It is a Serial Port Protocol Bluetooth working on Bluetooth protocol "Bluetooth V2.0+EDR". Brief descriptions of these modules are given in the table below: Hence hardware libraries and scratch extensions are developed as per the behavior of these modules. HC-05, HC-06, HM-10, and AT-09 are the supported Bluetooth modules with evive and other Arduino boards. Esp32 (ESP-WROOM-32, ESP32 development board, etc.).Arduino boards like Mega, Uno, and Nano.Receive commands from the device and play tones, songs, or other recorded files on your Smartphone.ĭabble is compatible with the following prototyping boards: Visualize and analyze the input and output signals given to the device using the oscilloscope module. Use the camera of your Smartphone for taking photos and videos, face recognition and color picking.Īccess different sensors of your Smartphone such as the accelerometer, gyroscope, proximity sensor, magnetometer, light meter, sound meter, GPS, temperature sensor, and barometer to make projects and conduct experiments. Provide analog and digital inputs via buttons, knobs, and switches. Remotely monitor the live status of devices and debug them.Ĭontrol actuators such as the DC motor and servo motor. Send and receive commands over Bluetooth.Ĭontrol devices in analog (Joystick), digital, and accelerometer mode. This getting started guide will help you to understand the required hardware/modules, wiring diagram, connecting the board/Bluetooth module with mobile, and how to use Dabble library/extension. Examples of codes are also provided in the Arduino library of Dabble. You can write the program in Arduino IDE or PictoBlox (graphical programming based on Scratch 3.0). You can use Dabble as a Bluetooth Controller App for Arduino Uno-Mega-Nano, ESP32, and evive for making various DIY projects or IoT applications. Dabble App transforms your Smartphone into a virtual I/O device and lets you control hardware using Bluetooth, communicate with it, and access sensors like accelerometer, GPS, proximity, and other features of your Smartphone.
