Arduino & ESP32 Bluetooth Cont

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, communicate with it, 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 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.
• Projects 🙂 (Coming Soon): Make dedicated projects to experience different concepts of the real world first-hand like home automation, line-follower and robotic arm.
