Zig + Arduino MQTT Mastery is now live on ZigSense Academy

If you've ever wanted to write embedded firmware without the baggage of C — no undefined behavior, no hidden allocations, no runtime surprises — Zig is your answer.

What this course covers:

• Setting up the Zig toolchain for AVR cross-compilation

• Driving real hardware: DHT22, BMP280, HC-SR04 sensors

• Implementing UART, I²C & SPI protocols from scratch in Zig

• Building a complete MQTT CONNECT + PUBLISH packet encoder by hand

• Wiring the full Arduino → ESP8266 → Broker pipeline

• Adding error handling, watchdog timers, and reconnect logic for production use

Who it's for:

Developers who think in systems, want to understand what's actually happening at the hardware level, and refuse to accept "it just works" as good enough.
