Circuit Playground Inspires 4-Year-Old’s Lemon Circuit – A Work of Art!
After watching episodes of Circuit Playground, Forums user devellison’s 4-year-old twins were inspired to build their own lemon battery, which they did:
But then they set out to improve the design to their liking, which they did!
They really wanted to do the lemon batteries, so we did. It worked, but only some LEDs would light up well (one of my newer 5mm blue LEDs did way better than my old scrap 3mm ones). With 6 lemons in series, we measured about 5V but less than a mA of current when lighting the LED. Then my daughter decided to improve the battery – while we’re still working on really getting the concept of a circuit at 4, I wasn’t about to stop her 😉
And they came up with the absolutely brilliant lemon work of art:
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.
