Arduino Projects
Build exciting Arduino projects: control LEDs, buzzers, sensors, motors, and create interactive systems

Join the AI Workshop to learn more about AI and how it can be applied to web development. Next cohort February 1st, 2026

The AI-first Web Development BOOTCAMP cohort starts February 24th, 2026. 10 weeks of intensive training and hands-on projects.

Put your Arduino knowledge into practice with hands-on projects. Learn to control LEDs, work with buzzers, read analog and digital inputs, control servo motors, and build a digital thermometer. Each project builds on your understanding of Arduino programming and electronics.
