Dabble is a versatile project interaction & Bluetooth controller app for Arduino, ESP32 & evive that replaces a wide variety of electronic components and exploits the inbuilt features and sensors of your Smartphone like the GPS, mic & accelerometer thus transforming into a virtual treasury of infinite shields & more. It lets you control & communicate with hardware via Bluetooth. It also provides you with dedicated projects compatible with Scratch & Arduino to help you learn by doing.

What Dabble has in store:

Currently Available Modules:
• LED Brightness Control: Control brightness of LEDs and digital/analog pins.
• Terminal: Send and receive textual and voice commands over Bluetooth.
• Gamepad: Control devices/robot in analog (Joystick), digital, and accelerometer mode.
• Pin State Monitor: Remotely monitor the live status of devices and debug them.
• Phone Sensor: Access 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.

Coming Soon:
• Motor Control (Coming Soon): Control actuators such as the DC motor and servo motor.
• Inputs (Coming Soon): Provide analog and digital inputs via buttons, knobs, and switches.
• Camera (Coming Soon): Use the camera of your Smartphone for taking photos, record videos, colour picking, and face recognition (coming soon).
• IoT (Coming Soon): Log data, publish it on cloud, and access data from API.
• Oscilloscope (Coming Soon): Visualize and analyse the input and output signals given to the device using the oscilloscope module.
• Music (Coming Soon): Receive commands from the device and play tones, songs, or other recorded audio files on your Smartphone.
• Projects (Coming Soon): Make dedicated projects to experience different concepts of the real world first-hand like home automation, line-follower, and robotic arm.
