hello everyone , in this tutorial I will show you how to build a RTTTL player ,and I will show you how to do that using Teensy 3.1 .
You can expand the number of the songs you want to add , and will show you how to do that later and give you a resources for more than 10K files.
The Teensy is a complete USB-based microcontroller development system, in a very small footprint, and run on a 32 bit ARM M4 MCU , and can run on a frequency up to 96MHz.
the size of the Flash Memory is 256K , 64K of RAM and 34 GPIO , that’s make it the best choice for such a project, I will add more audio files and draw more complex GUI later “and you can do as well”
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.
