Silly Job Title: Component Wrangler. I am the Component Wrangler!

In this video we continue to work our way through Learning the Art of Electronics. We have nearly finished the 1N DC Circuits chapter. Today we learned a new rule of thumb: when circuit A drives circuit B the output impedance of circuit A should be equal to or less than 10% of the input impedance of circuit B.

There is no prac this week, only theory. Next week we will complete this chapter and then we’re ready to proceed into our first lab chapter.

In this video we demo the KY-002 Vibration Switch Module. There’s more info here: KY-002 Vibration Switch Module on ArduinoModulesInfo.

Source code is here: 2025-10-13-KY-002-Vibration-Switch.ino.

We use the Rigol MSO5074 Mixed Signal Oscilloscope to check the output signals.

We use the Riden RD6006 Bench Power Supply for power.

We use the EEVblog BM2257 Digital Multimeter to test voltage.

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