Sometimes in my science shows I use dangerous chemicals.
so I think it sounds fun to make the ultrasonic sensor sense any child who is trying to be close to me and alert them by saying or emitting light.

software i used it to write the code of my
Ultrasonic sensor, there is a lot of sensors that we use to detect object but it's special because we can use it to measure how far is objects
By measuring the duration by which Ultrasonic waves hit object and bouncing back.
software to simulate my circuit and try it.

ultrasonic has 4 pins So
power so connect it to 5V
cathode so i connected it to ground
trig and echo connect it to 3,4 pins in arduino
servo motor has 3
one pin for the volt and one GND
the third connected to 2
The two lamps
one side to resistor and GND the other for arduino pins

our friend mahmoud learnt us about the work idea of 7 segment and how we use it .

I have faced a problem in the code of ultrasonic sensor
I solved by searching
I didn't use the > in the math block and that made the code didn't work but after searching i changed it
