Raspberry Pi, Arduino, and Learning Linux

From a channel Lumen includes in full: Lewis Loflin's plain, practical circuit tutorials (transistor drivers, H-bridges, 555 timers, regulators, Hall sensors) with full schematics and bench verification; no hype, just working circuits explained.

A 17-minute video from Lewis Loflin's catalogue; the title names its topic.
