Young inventors and their parents will be able to master the basic principles of electronics and learn how to control an Arduino board. The master class "Code and Schemes" is a great opportunity for children and parents to dive together into the fascinating world of electronics. Participants will get acquainted with the Arduino platform, learn how to connect the board, work with sensors and actuators, as well as write simple control programs. The event is aimed at beginners, those who are just taking their first steps in programming and technical creativity. The class is built on the principle of practical immersion. The staff of the MediaLAB hall will explain the basics, and then, under the guidance of teacher Artem Bazhin, participants will be able to implement their first mini-projects themselves. If a child finds it difficult to cope alone, parents can actively help. Such a master class helps develop logic, creative thinking, and attentiveness. It will be interesting for schoolchildren and adults. All materials are provided, and if possible, it is advisable to bring a laptop.
