we have there is such a board called arduino uno, you could see it with us in a blue color. this is a very convenient board for teaching children to build prototypes of various automatic devices without soldering. schoolchildren connect various devices to this board and program it on the computer. they plan the subject. to study until the 11th grade, every year they will consider more difficult topics and even try to create their own printed circuit boards ; during the lesson, they follow the key rule with electronics: be careful and avoid short circuits. i like it because i have never seen such a subject in other schools. if you try to understand, everything will be fine, but it's a little difficult when we connect something. new technology work is my favorite. lesson i pretty much understand everything here, so far it's not difficult to do here, it's very cool. there are a lot of different e-e devices, for example, computers, all kinds of electric greenhouses, before i didn't know so much how to connect it now it's been three weeks, so i know better , it's interesting to i
