Distance learning vs COVID-19.

Friends! As part of distance learning, because of COVID-19, I have to teach lessons remotely . I gave my students tasks to come up with program code for a device that I prepared for them in my Arduino home lab. It consists of two RGB LEDs, a sound speaker and a servo. The guys sent me their programming codes. I have selected four of the best software codes. Let’s see what happened! I ask you to choose the best functioning program code. Vote for comment № 1 or № 2 or № 3 or №4. Sincerely, Yuri Kovalenok. #d
