For the first couple of years he spent thousands of hours struggling to learn programming languages to automate his backyard mini-farm. Then while speaking at an international conference (along with Eric Maundu and Rob Torcellini, he’s among the elite few experimenting with aquaponics and automation) he was introduced to APDuino(open-source firmware for aqua- and hydro-ponics).
APDuino allows Kretzinger to read the sensors in his garden without any programming. Now Kretzinger’s garden can send him tweets or Facebook updates if something is going wrong and Kretzinger can adjust the water flow, pH and temperature from a smartphone.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
