Ok, this is an embarrassing problem. I’m using AVR Studio 6.1 beta (6.1.2440), and about every 5-10 times I build my solution, the Benny Hill chase music starts playing! I have visual studio 2010, and it doesn’t do it. I’ve googled for viruses, but found nothing. Windows defender found nothing. (My box is pretty well locked down – I don’t run as administrator). It seemed to start happening after I installed the LUFA via the gallery – this may be a coincidence. Have I found an easter egg? Can it be turned off?
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.
