Electronics explained in a simple way
If you were following my newsletter 2-3 years ago, you might remember 9 Circuits.
That was a very popular ebook I wrote and sold back then.
So when No Starch Press approached me suggesting we should create a new book together based on 9 Circuits, I thought:

Christmas is coming up in about a month. And it’s time to build some Christmas things with electronics.
So I just added a new course project to the Ohmify library: The Blinking Christmas Lights

I cannot count how many times I’ve connected my battery to a freshly built circuit and…
…nothing.
In the last email I sent last week, my goal was to convince you to try and build the blinking light circuit.
Here are the build instructions:

So, did you do it?

[GARRY]:
“When I measure the voltage of my 9V battery using my multimeter I get a reading of 9.06 when it is not connected to any circuit. When I hook the battery up to a simple circuit (i.e. 325 Ohm resistor in series with a red LED) and measure the voltage drop across the battery I get a reading of 8.65 V – why the difference?”
Ok, I’ve been away from electronics for too long.
I haven’t been able to get my hands dirty and build circuits for a while.
But last week I sat down to build some circuits for the 555 Timer course.

Building a circuit and understanding a circuit are two different skills.
And you can learn one without the other.
As a kid, my dad taught me how the relay works. That helped me understand a simple circuit to blink a light. And we built it together.
