Learn C for Embedded Systems
Bits, registers, and timing, on the metal, in C. Built for firmware and hardware engineers. You write real C, run it in the browser, and watch it pass. No installs, no toy apps, no lectures.
11 projects, 275 hands-on levels, first project free.
Problems you will solve
- set and clear hardware register bits
- debounce a physical button
- drive a peripheral over a bus
By the end you can program microcontrollers close to the hardware.
What you will build
- Foundations: code through embedded systems
- Bits & Registers
- GPIO & Digital I/O
- Timers, PWM & Delays
- ADC & Sensors
- Serial Communication & Protocols
- Interrupts & Scheduling
- State Machines
- Constrained Memory
- Embedded Control
- Capstone: Smart Thermostat Firmware

Frequently asked questions
Do I need to know how to code to start Embedded Systems?
No. The Embedded C: Firmware from Scratch track starts from the fundamentals and builds up, and the first project is free.
Do I need to install anything?
No. Every level runs in your browser and is graded the moment your code works. No C install, no setup.
What language will I write?
C. You write real C, run it, and get instant feedback across 275 hands-on levels.
Is it free to start?
Yes. The first project is free with no card. Unlimited access to all 33 tracks is $12 a month or $100 a year.
