ACTIVITY DESCRIPTION
We know that looking closely at the television and computer screen hurts our eyes. however, adults and children look at the screen and damage their eyes. We did this project for it. The ultrasonic sensor, which detects an object as close as 30 cm to the screen, notifies the relay that the electricity is cut off. When the object goes 30 cm away, it gives the screen the electricity by the same method. Due to 220 v of electricity is used in this study, students should definitely work on parent / teacher control.
You can use the mBot original kit, instead of using Arduino components.
The ultrasonic sensor will detect and compare the distances between a person and the screen. The objective is to check if this person is too close to the screen, and if he/she is so, to give a warning and stop the game.
