Adafruit has delivered another in their fantastic educational electronics series called Circuit Playground. They’re working their way through the alphabet, explaining the principals of electronics in ways that even children can understand. These videos are a great way to introduce kids to the basics (and safety information) involved with electrical components.
In this episode, they tackled the letter G, which stands for ground. As Limor explains to Adabot, grounding simply means that something is connected to the earth. A surprising amount of things around us are grounded, as Adabot discovers.
This series does a fantastic job of relating the principles of electronics to children. The bite sized bits of information mixed with the adorable puppet design are a perfect combination for inspiring young minds. Keep up the good work Adafruit!
If you missed the letters A through F, why not take a few moments and watch them all below?
Here’s a quick peak at what Adabot learns in the other videos:
“A is for Ampere” Ampere describes the number of electrons that flow through a circuit in one second. It is named after Andre-Marie Ampere.
“B is for Battery” Batteries give us electricity on the go without needing to plug into a wall socket. They are filled with a bunch of components that generate electrical current.
“C is for Capacitor” A capacitor stores electrical energy. While similar to a battery, a battery generates electrical energy using chemistry while a capacitor has to be charged from an external source before it can provide electrical energy.
“D is for Diode” By placing a diode at the circuit’s power input we ensure that the current can only flow in one direction, the correct direction that we’ve designed the circuit to work with.
[There currently is not a video for “E.”]
“F is for Frequency” Frequency is how often something happens over time. We measure frequency in units called hertz.
