In this Arduino Tutorial we will learn how to build custom Android applications for controlling Arduino using the MIT App Inventor online application.
For this tutorial we have two example. The first example is controlling a simple LED and the second one is controlling a Stepper Motor using the smartphone. In my previous tutorial we already learned how to make the Bluetooth communication between the Arduino Board (visit Tutorial) and the Smartphone using the HC-05 Bluetooth module and explained the Arduino code needed for the first example.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
