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.

Continue reading

Power is the rate of doing work, and for electricity, that means the rate in which energy is converted in a circuit.

Continue reading

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.

I have used the Leonardo/32u4 for years. Having said that, I would still point newbies to the Uno/328p to start and then push them to…

With the walls of full stacks and pyrotechnics, I'm guessing it should do a great job detecting Angus too. Thanks for this post title,…

Hmm... stating the obvious: That new detector module really puts the "spark" into "SparkFun"!!!

Oh, also check out the LiPo USB car starters. They will put out some current!

I bought a Raspberry Pi UPS board and found that had a pretty good little charger; it'll put out some current too. I won't paste the link…

Thank you, very helpful and concise article. From a project cost perspective, the LiPo usb battery pack can charge a battery and provide 5V…
