One of my current academic work is to build up a water level sensor with Arduino Uno, a breadboard, an ultrasonic distance sensor, micro servo, 2 resistors and 2 red LEDs. I already wrote some code, but I need some guidance towards how to structure each section my code properly in order to make ever…

The purpose of the project is to prevent the overflowing of water of a government reservoir by detecting water level using the components that I have mentioned in my question.

2 resistors and 2 LEDs .... hmmm :thinking: what can this mean ?

Sorry, I forgot the mention that the sensor controls the opening and closing of the resevoir floodgate in order to maintain the proper water level.

in your sketch are LEDs not mentioned. Are they not connected to arduino?

Sorry, I didn't quite catch what you have written.

All the components are meant to be connected, but I don't know how to connect them altogether properly in terms of structuring the code and the Arduino board.

I have just asked my tutor about the LEDs and he said that one LED should be green when the floodgate opens and the red is to alert the distance of the water. Both LEDS should work alongside with the micro servo. I will change the colour of one of the LEDs into green.

How to properly connect the ultrasonic distance sensor, micro servo, resistors and LEDs to Arduino Uno using the breadboard?

What is the purpose of resistors? why they stay independent?
