What a Embedded Systems intern does

The Embedded Systems role, what you build at each level and what you need before you start.

Program microcontrollers and build embedded products: GPIO, ADC, PWM, interrupts, UART, I2C, SPI, ESP32 Wi-Fi, RTOS and PCB design.

What you build, level by level

Level 1: Foundations: What embedded systems are, Set up a toolchain, Digital input and output and more.
Level 2: Building real features: I2C sensor, SPI device, Register-level programming and more.
Level 3: Professional work and capstone: RTOS basics, STM32 or ARM Cortex-M, Bootloader and OTA and more.

Where this work is used

Training Trains, W3AppDevelopers and DomainHostly use these skills in real projects: IoT Solutions. Interns who pass the readiness check can take paid-company work from the Company Work board in the portal.

Before you start

ECE and EEE students are a natural fit. Basic C helps. A simulator (Wokwi) can replace hardware for early tasks.
