Duration 2 days – 14 Hours
Overview
This hands-on course introduces learners to Raspberry Pi fundamentals and Python programming for building simple electronics and IoT-style prototypes. Participants will learn how to set up a Raspberry Pi, write and run Python programs, safely use GPIO pins, and control/read common components such as LEDs, buttons, buzzers, and basic sensors. By the end, participants will complete guided mini-projects that combine Python logic with real hardware interaction.
Objectives
- Set up and configure a Raspberry Pi for development (desktop or headless)
- Write, run, and debug Python programs on Raspberry Pi
- Understand GPIO pin mapping and apply basic electronics safety
- Control common components (LEDs, buzzer, servo—optional) using Python
- Read inputs from buttons and basic sensors and handle noisy data
- Build a small working prototype that integrates input + logic + output
