The case for formalizing free exploration opportunities
There are two basic ways to connect electronic components with two terminals: series and parallel. In this episode, we examine those two types of circuits and show how to calculate equivalent resistance.
Power is the rate of doing work, and for electricity, that means the rate in which energy is converted in a circuit.
Let's look at the resistor and how it affects current and voltage in a circuit. Here's a hint: if you know two of either voltage, current or resistance, you can solve for the third.
In this episode, we'll explore how electric current flows through a circuit.
Over the next few weeks, we'll explore the basics behind electricity in a series of videos.
Let's dissect another section of EdiBot 2.0 and learn how to spin DC motors with Python.

Adding a chronograph to a Hot Wheels track to measure the speed of passing toy cars.
I finally had some time late yesterday to watch a couple of the videos on YouTube that reviewed the "pre-release" samples of the RPi 5 that…
OK, found an "implication of an answer" -- over on Adafruit's "New Products" list is [Raspberry Pi 5 RTC…
I'm kind of "chomping at the bit" to know more about the RTC battery requirements for the RPi 5. From the pics on the "official documents"…
YAY! Finally a Pi with a built-in RTC! FINALLY -- this has been one of my "hot button" issues for many years. Now if we could only get the…
FWIW, I decided to order 2 of the 8GB "kits", as at $114.95 each, they'll each qualify for "free shipping" even if they don't both get…
If you pre-order more than one of the RPI 5 items, will they all ship at the same time?
It seems to me that somewhere in the text, you should have included a link to [back]order the [Experiential Robotics Platform (XRP) Kit -…
Where can i get the project code that was running on the RP2040? I would like to use the T1L and Ethernet modules on a similar demo? I'm…
Another thought occurred to me as I was getting out of bed (about half an hour ago -- I'm NOT a "morning person!): Use "AI" to be able to…
A couple of "conspicuous by their absence": First, our friends over at Adafruit have a LOT of items that have…
