| This is for beginners and very much by a beginner / hobbyist.
It's intended to get an intuitive overview for hobbyist needs. It may get you started, but to be able to do anything remotely clever, follow a proper course or read a good book.
Some basics and reference:
Volts, amps, energy, power · batteries · resistors · transistors · fuses · diodes ·
capacitors · inductors and transformers ·
ground
Slightly less basic: amplifier notes · varistors ·
changing voltage · baluns ·
frequency generation ·
Transmission lines · skin effect
And some more applied stuff:
IO:
Input and output pins · wired local IO · wired local-ish IO · · Various wireless · 802.11 (WiFi) · cell phone
Sensors: General sensor notes, voltage and current sensing ·
Knobs and dials ·
Pressure sensing ·
Temperature sensing ·
humidity sensing ·
Light sensing ·
Movement sensing ·
Capacitive sensing ·
Touch screen notes
Actuators: General actuator notes, circuit protection ·
Motors and servos ·
Solenoids
Noise stuff: Stray signals and noise · sound-related noise names · electronic non-coupled noise names · electronic coupled noise · ground loop · strategies to avoid coupled noise · Sampling, reproduction, and transmission distortions
Audio notes: See avnotes
Platform specific
- Arduino and AVR notes · (Ethernet)
- Microcontroller and computer platforms ··· ESP series notes · STM32 series notes
Less sorted: Ground ·
device voltage and impedance (+ audio-specific) · electricity and humans ·
power supply considerations ·
Common terms, useful basics, soldering ·
landline phones ·
pulse modulation ·
signal reflection ·
Project boxes ·
resource metering ·
SDR ·
PLL ·
vacuum tubes ·
Multimeter notes
Unsorted stuff
Some stuff I've messed with: Avrusb500v2 ·
