It’s probably not a faulty chip

I’d been working on this circuit ALL day.

Then I plugged it in, and it didn’t work…

“Why is it not working??!!”

“It must be a faulty chip”, I told myself.

“I should go down to the electronics shop and complain.”

But I decided to take a break first.

After the break I thought:

“Hmmm… maybe I should recheck my connections?”

“I always tell my student to triple-check their connections”

So I did.

And well, it turned out I was using one of those breadboards that has the power supply columns split into two halves. So I lacked a connection between the two.

The moral of the story? Triple check your connections ;)

Keep On Soldering!

PS! Last week I launched Ohmify. It’s now closed for new members, but I’ll let you know when I open for more members in the future.

PPS! If you want to get started building electronics projects, I recommend checking out my eBook Getting Started With Electronics: https://www.build-electronic-circuits.com/products/ebook-2nd-edition
