Back in August, you may have read my article regarding the AVR based Attiny2313/ Attiny84/ Attiny85 USB Volume Controls.
The article appears to be pretty popular on various websites, including a nice mention on the Adafruit Blog.
With the release of the Adafruit Trinket (Attiny85 based) a tutorial is now available on the great Adafruit Learning System for a Trinket USB volume control example.
After Purchasing a Trinket to experiment with and Adafruit having a great mentality for Open Source Hardware, I decided to modify my own Attiny85 volume control PCB to make it compatible with the Trinkets 5Volt firmware (flash_me_hv_5volt.hex)! (which is Arduino compatible) This gives access to direct programming without the need for a separate programmer from the Arduino IDE. Its also nice to support the hard work done at Adafruit by purchasing one of their Trinkets.
Very cool project!
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
