OptionsAbout Projects for Teens & Makers (12+)
When the boxed science kits get too easy, these are the next step. They involve real electronics and real code: Arduino-controlled robots and drawing machines, ESP32 boards that talk to AI models, analog and digital electronics labs, and TTL computers you build chip by chip and then program.
Some need soldering and some do not; each product page says what tools and skills a build needs. They are well suited to secondary-school technology classes, robotics clubs, makerspaces and anyone who wants to understand how the devices around them work.
