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!
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.
