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.

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.
