Decades of research and everyday experience offer striking examples of the interplay between mind and body. Around the time Pavlov was experimenting with drooling dogs, the American physician John Mackenzie watched one of his patients develop an itchy throat and struggle to breathe upon seeing an artificial rose — suggesting that the perception that pollen was present was enough to provoke her allergy symptoms. In the 1970s, scientists discovered a similar phenomenon while conducting taste-aversion experiments on rats: They repeatedly gave the animals an immunosuppressive drug along with the artificial sweetener saccharin; eventually, they found they could quell the animals’ immune activity with saccharin alone. Many of us can recall times when the mere scent of a food that once made us sick could trigger nausea anew.

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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
