Silly Job Title: Wire Whisperer. I am the Wire Whisperer!

Today is Module Monday.

In this video we take a look at the Smart Electronics Soil Moisture Hygrometer Detection Humidity Sensor Module For arduino Development Board DIY Robot Smart Car.

The code for this Arduino sketch is here: 2025-12-01-HW-103-Water-Level.ino.

We use the METCAL PS-900 Soldering Station for soldering.

We use the Yizhan Digital Microscope to take a close look at our module.

We use the ElectroCookie PCB Prototype Solderable Breadboard to make our LED traffic lights circuit.

We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.

We use the Plato Model 170 Wire Cutter as a wire cutter.

We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Errata: at t=22:58 I say I need smaller “capacitors” but what I meant is smaller “resistors”.
