Embedded Systems Mastery Path¶
A structured, module-wise embedded systems training program that takes you from blinking your first LED to designing production-grade, master-level firmware — starting with Arduino/ESP32 and C/C++, with real compilable code in every module and a hands-on project at the end of each level.
No hardware required to start. Every Level 1 example runs in the free Wokwi online simulator — a browser-based Arduino/ESP32 simulator with virtual LEDs, buttons, sensors, and displays — and works unchanged on real boards when you get one.
How the program is organized¶
| Level | Focus | Modules |
|---|---|---|
| Level 1 · Entry | Arduino/ESP32 with C/C++: GPIO, PWM, serial, I2C/SPI sensors, interrupts, WiFi | 9 topics + 1 capstone |
| Level 2 · Intermediate | FreeRTOS, ESP-IDF, BLE, MQTT, OTA updates, filesystems, robust firmware | 9 topics + 1 project |
| Level 3 · Advanced | Bare-metal ARM/STM32, registers & linker scripts, RTOS internals, DMA, PCB basics | 9 topics + 1 project |
| Level 4 · Master | Production firmware, secure boot & OTA at scale, TinyML, RF design, manufacturing | 9 topics + 1 capstone |
How to use this site¶
- Work through each level in order — later modules assume earlier ones.
- Every topic page has real, compilable Arduino C/C++ sketches — paste them into the Wokwi simulator (or the Arduino IDE with a real board) and run them as you read.
- Each level ends with a project that combines everything learned in that level.
- Use the search bar (top of the page) to jump straight to a topic.
