About this app

Whether you're a student, a teacher, or a hobbyist, Dabble is the perfect app for all your DIYing needs. It transforms your Smartphone into a virtual I/O device and lets you control hardware via Bluetooth as a gamepad controller or joystick, communicate with it like a serial monitor, access sensors like accelerometer, GPS, and proximity and other features of your Smartphone. It also provides you with dedicated projects compatible with Scratch and Arduino to help you learn by doing.


What Dabble has in store:

• LED Brightness Control: Control brightness of LEDs.
• Terminal: Send and receive text and voice commands over Bluetooth.
• Gamepad: Control Arduino projects/devices/robot in analog (Joystick), digital, and accelerometer mode.
• Pin State Monitor: Remotely monitor the live status of devices and debug them.
• Motor Control: Control actuators such as the DC motor, and servo motor.
• Inputs: Provide analog and digital inputs via buttons, knobs, and switches.
• Phone Sensor: Access different sensors of your Smartphone such as the accelerometer, gyroscope, proximity sensor, magnetometer, light sensor, sound sensor, GPS, temperature sensor, and barometer to make projects and conduct experiments.
• Camera:Use the camera of your Smartphone for taking photos, record videos, colour picking, and face recognition (coming soon).
• IoT : Log data, publish it on cloud, connect with internet, set notifications, and access data from APIs like ThingSpeak, openWeathermap, etc (coming soon).
• Oscilloscope : Wirelessly visualize and analyse the input and output signals given to the device using the oscilloscope module.
• Music Tune : Receive commands from the device and play tones, songs, or other recorded audio files on your Smartphone.

Make dedicated projects to experience different concepts of the real world first-hand like home automation, line-follower and robotic arm.

Ratings and reviews

Like the app, but i am having resolution issues with the gamepad joystick. For instance, there seems to be a large dead band when moving the stick at the midway points where the stick is 45 deg. From either horizontal or vertical in all 4 quadrants. The joystick outputs values that are equal in both X and Y for a large range in these areas. Makes finite control more difficult. Perhaps, this is an error in communcication with my hc06, but i dont think that is the case.

It worked on previous phones but now just crashed when opened on a pixel 8 pro. It looks like it needs to be updated to support newer phones. I have a number of kids stem projects that seem to be at a dead end because there is not a current version of the app. Would love to see an update.

I was previously using other apps to control my robot wirelessly but it was very tough to the interface. This is very easy to use app with a lot of use cases and documentation available for everything on their website. Edited - New version of the app is very stable for use. Not it also automatically connect to the hardware. Thanks for the update.
