What the app is and who it suits
Dabble is a companion app for hobby electronics. It runs on an Android phone and sends commands to a microcontroller over Bluetooth, so the phone acts as the control panel for a homemade device.
The developer, STEMpedia, names students, teachers and hobbyists as its audience. The listing presents it as a tool for DIY projects and for learning by building.
Controlling a microcontroller from the phone
The app can act as a Bluetooth gamepad or joystick, so buttons and sticks on the screen send input to hardware. The listing describes this for driving things like robots.
Its virtual shields are on-screen controls set up for specific jobs, including robot control, camera use and IoT. The listing does not say which boards or firmware each shield needs.
Sending and reading serial data
A terminal mode works like a serial monitor, letting you send text to a connected board and read what it sends back over Bluetooth.
This makes it a way to check a sketch or exchange values with hardware without a laptop cable attached.
Using phone sensors as inputs
The app can read the phone's own sensors, including the accelerometer, GPS and proximity sensor, and pass those readings to a connected board.
The listing also mentions access to other phone features, so a project can use the phone's hardware in place of extra modules.
Scratch and Arduino projects for learning
Dabble includes dedicated projects built for Scratch and Arduino. The developer presents them as a way to learn by building something working.
Students working through Scratch first can move to the Arduino projects, which use the same phone controls with real hardware.
