Welcome back everybody! Be sure to subscribe! In a previous tutorial, I used a premade model railroad current sensor combined with an arduino to detect current. Today I am building a DIY model railroad current sensor from scratch that can detect current using a combination of hardware and code to achieve this. This is a far more cost effective way to do current sensing!

“The godly may trip seven times, but they will get up again.
But one disaster is enough to overthrow the wicked.
Don’t rejoice when your enemies fall;
don’t be happy when they stumble.
For the Lord will be displeased with you
and will turn his anger away from them.
Don’t fret because of evildoers;
don’t envy the wicked.”

Proverbs 24: 1619 NLT
