Dad’s ‘Daddy Science Day’ Experiments with His Daughter – First Up, Fruit & Veggie Batteries
A great story from Daniel Eichhorn explaining a ‘lemon battery’ experiment to his daughter. We love stories like these.
My goal was to demonstrate electricity to my daughter with something a little bit more understandable than the readings from a multimeter, since she cannot read the numbers yet. So, as suggested in the Wikipedia article I wanted to get an LED to shine. 0.9V wouldn’t be enough to make that happen, so we got a few more lemons and put them into series:
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.
