Electronics roadmap

Embedded C, microcontrollers, communication interfaces, RTOS, plus analog & digital electronics and semiconductors.

Start with Analog Electronics, follow the steps in order, then build a project, prepare for interviews and earn your certificate.

Foundations

  1. Analog Electronics — Circuit fundamentals, semiconductors and diodes, BJTs and MOSFETs, op-amps, filters, feedback and oscillators, power and regulators, noise and precision, ADC/DAC interfaces, analog IC design, PLLs, PCB/EMI, SPICE, debugging and capstone projects — the physical layer everything digital eventually depends on.
  2. Semiconductor Devices — Semiconductor physics, PN junctions and every diode family, BJTs, JFETs, MOS capacitors, MOSFETs, CMOS, FinFET/GAA, power devices (IGBT, thyristors, SiC, GaN), RF and optoelectronic devices, sensors, memory and emerging devices, fabrication and packaging, reliability, characterization, SPICE models and device selection — the physics behind every chip in every other track on this page.
  3. Digital Electronics — Boolean logic, combinational and sequential circuits, flip-flops, counters, memory, timing and the building blocks that eventually become a processor — plus a Verilog/HDL module and a full interview-prep and design-challenge track.

Core skills

  1. Embedded C — C for microcontrollers — the C foundations you need, then fixed-width types, register bit operations, volatile, memory-mapped I/O, GPIO, interrupts, SysTick timing, ring buffers, drivers, startup code, linker sections, fixed-point and MISRA-style reliability, with real code compiled for an ARM Cortex-M4.
  2. Microcontrollers — How a microcontroller actually works: GPIO, timers, interrupts, ADC, PWM and peripherals, built up from first principles.
  3. UART Communication — Asynchronous serial communication
  4. SPI Communication — High-speed synchronous peripheral communication
  5. I²C Communication — Two-wire communication between controllers and peripherals

Advanced

  1. Real-Time Operating Systems — Tasks, scheduling, mutexes, semaphores and queues — how a real-time operating system keeps dozens of things happening on time, on hardware with no room for a full OS.
  2. CAN Bus — Robust multi-node communication used heavily in automotive systems
