For some purposes i thought it would be very nice to enable some telecommunication abilities on raspberry pi. For example if something does not work as it should (e.g. average load too high, temperature/humidity too high) raspberry pi can call you. Or if you just want to control something quickly via phone (e.g. starting a process, reboot or open the door) – raspberry pi can answer your calls and made it for you. Of course you can make it via SMS or web-interface, too – but for example a call often gets more attention than a sms.
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.
