Zigbee

A low-power mesh in one real house: the shared radio, three roles, names and temporary addresses, joining, paths that form and change, a sleepy sensor and its parent, clusters, bindings, security, the hub, failure, and the ESP32 on the bench.

LoRa

Small messages over a longer link, on one real Australian farm: the chirp, spreading factor, bandwidth and coding, airtime, decoding below the noise but not through interference, the rules where you live, collisions, a battery day, LoRa against LoRaWAN, and the ESP32 on the bench.

Wi-Fi

How a frame crosses the air, as a ripple tank where floats are stations and the access point is moored at the edge: channels on a strip along the rim, signal on a meter, finding and joining a network, station and access point, taking turns, hidden stations, rates, sleep and security, then the ESP32 on the bench.

Ethernet

How a cable carries a network, as a radio room on one channel and then a dispatch desk with a line for each station: collisions and back-off, what a frame holds and who it is for, hubs and switches, then the real hardware, the link, the MAC, the PHY and RMII, and the three ways an ESP32 gets Ethernet.

CAN bus

How many devices share one pair of wires with no master, as a hall of desks that shout or stay quiet around a two-wire rail: who speaks first, how a message is built and checked, what goes wrong, and the two ends of the rail.

RS-485 and Modbus

How a serial line is made to reach far and serve many, as a workshop bench with numbered stations and a two-rail gauge: a difference between two wires, one driver at a time, the two ends, and the Modbus conversation on top: addresses, requests, tables and the number trap.

UART

How two devices send bytes down a wire with no clock, as two cottages joined by two wires and a ground: the idle line, the start bit, the data bits, baud, sampling in the middle of each beat, and what goes wrong when the settings disagree.

TCP and UDP

What a network adds to your data and what it leaves out, as a classroom: addresses and ports, one-line cards that may be lost, and a novel cut into numbered strips that the receiver pastes back together, acknowledges and slows down for.

Screens

Every way a screen is fed, from a two-wire OLED to a laptop's eDP panel: how much data a picture is, where the picture lives, the frame buffer, RGB timing, tearing, and the fast links of MIPI DSI, LVDS and eDP.

SPI

The four-wire bus that chips use when they need speed, as a conveyor-belt sushi restaurant: the belts, the clock, a byte each way at once, the light that says who listens, the four modes, and the wider belts of dual, quad and octal flash.

MQTT

How a sensor's reading reaches a phone, a laptop and a lamp without any of them knowing the others, as a post office: topics, subscribing, wildcards, retained letters, registered mail, check-ins, a last will, and who gets through the door.

I2C

The two-wire bus nearly every sensor module speaks, from the beginning: why a bus, who talks, the clock, addresses, a whole read of a temperature, and the pull-up resistors that make it work, shown as water in pipes.
