This Instructable will be about designing a music player from using various building blocks. You will understand the communication between the microcontroller, memory, computer, LCD display, RTC, IR remote, and the music file decoder. I will try my best to to teach you in a way so that you can design your own projects using the skills you learn, without blindly following instructions.
I know most of you will simply glance at this first page and maybe skim through the rest. This Instructable has 18 steps and 5 appendices, with about 90 files and pictures. I sincerely hope you explore all my efforts.
Every step will be accompanied by a demonstration of that particular building block working. The source code will be provided. I will post the debug output, pictures, screenshots, USB device and packet analysis, and logic analyzer waveforms. NOTE: if the images look too compressed, don’t worry, they are included inside my .ZIP files too.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
