Proiectul acesta va masura turbiditatea din apa si va afisa pe un ecran lcd cat de pura este apa. De asemenea, se va aprinde un led RGB cu culoarea verde, galben sau rosu si va suna un buzzer. Este util deoarece poate detecta daca apa de la robinetul de acasa este buna de baut sau poate detecta cat de pura este apa unui lac.
Voi conecta la Arduino turbidimetrul si ii voi lua valorile care vor fi procesate si transformate intr-un procentaj de la 0 la 100. Pe baza acestui procentaj se va aprinde led-ul RGB, buzzerul si va arata acest procentaj pe LCD.

List of components:
- Arduino UNO R3
The Arduino IDE (Integrated Development Environment), a software tool made to make it simple to write, upload, and debug code for the board, can be used to program the Arduino UNO, which can be used to control a variety of electronic devices, including sensors, motors, lights, and other components.
- LCD 1602
A 16×2 LCD display module (LCD 1602) is a device that can be used to display alphanumeric characters, symbols, and even simple graphics. It has a display size of 16 columns and 2 rows.
- Passive Buzzer
A passive buzzer is a type of electronic component that is used to generate sound in electronic circuits. It is called passive because it does not have an integrated oscillator circuit and requires an external signal to produce a sound. The buzzer consists of a piezoelectric element that vibrates when an electric signal is applied to it, creating a sound wave.
- Turbidity Module (+Turbidity Sensor)
A turbidity module is a sensor used to measure the level of turbidity, or cloudiness, in a liquid. It works by shining a light through the liquid and measuring the amount of light that is scattered by particles in the liquid. The more particles there are, the more the light will scatter, and the higher the turbidity measurement will be.
-RGB LED
Three distinct LED chips—one each for red, green, and blue—are housed inside an RGB LED. A variety of colors can be created by independently altering the brightness of each of these hues.
Other components:
- USB Cable
- 10k and 330 ohm resistors
- Potentiometer
- Wires
- Button
