Silly Job Title: Plugerinerer. I am the Plugerinerer!
In this video we continue to work our way through Learning the Art of Electronics. In this video we finish the first chapter 1N DC Circuits.
Today we do some experiments to verify Kirchhoff’s Voltage Law.
We use the Riden RD6006 Bench Power Supply for power.
We use the Fluke 17B+ Digital Multimeter to measure current.
We use the EEVblog BM2257 Digital Multimeter to measure voltage.
We use the EEVblog BM036 Digital Multimeter to measure current.
We use the Sharp EL-546L Scientific Calculator to crunch some numbers.
We use the Multicomp Pro MP701033 Resistor Decade Box for variable resistance.
We use the Carpenter Mechanical Pencil to make our notes.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

You only need GET (and its little brother HEAD) and POST. Whether operations on a resource are idempotent or not is something that you might like to change. Send all operations through POST which will apply business logic and don’t use PUT or DELETE. Simple.

In this video we take a look at the 1-10pcs KY-035 Analog Hall Magnetic Sensor Module 49E For Arduino.
You can learn more about the Hall effect which is basically a magnetism detector.
The code for this Arduino sketch is here: 2025-10-27-KY-035-analog-hall-effect.ino.

DRV8833 Motor Driver
Over on one of my recent Hackaday articles I was referred to this article: DRV8833 Motor Driver. It discusses using MOSFETs as an alternative to BJTs for driving motors, thereby being more efficient.
