It’s been a month since my last post about my Arduino music player and remote. This is a music system geared towards performers, like magicians, ventriloquists, jugglers and the like who perform a one man/woman show and need an easy way to queue up and play music and sounds. It uses two packet radio Arduino devices, one that stores the music on an SD card and is hooked up to a speaker system, and the other that provides buttons and a display that controls the music. The project has been coming along nicely since my last post, and I am quite pleased with the results so far. Since the last post, i have made significant software improvements and also created a 3D printed case for the remote. I also informally tested the range of the remote, which uses packet radio to communicate with the base receiver. My test showed a range of about 250 feet with an unobstructed view. In comparison, Bluetooth’s unobstructed range is about 33 feet.
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.
