You have an older home theater receiver with an S/PDIF input (optical or RCA) and want to play movies with DTS or Dolby Digital soundtracks? This guide shows how you can get 5.1 sound output from a Raspberry Pi even if your AV receiver does not feature an DTS/AC3 capable HDMI input.
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.
