Silly Job Title: Bench Master. I am the Bench Master!
In this video we take a look at the HW-028 Rain Drops sensor module: Separate PCB Board Raindrop Module Sensor Rising Water Level Detection Module Raindrop Sensor Board. Project doco is here: HW-028.
We found some instructions and tutorials, including these:
- Arduino – Rain Sensor – Servo Motor
- Arduino Modules – Rain Sensor
- Rain drop Sensor Module
- How to use the Raindrop Sensor Module
Also we noted the use of the LM393 comparator on the module.

Silly Job Title: Solder Soldier. I am the Solder Soldier!
In this video we make a power cable running a DC barrel female socket into hook-clips.
We use the METCAL PS-900 Soldering Station for soldering.
We use the Riden RD6006 Bench Power Supply to provide power for testing.
We use the EEVblog BM2257 Digital Multimeter to test the cable.
We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
