| - | ===== Rezultate Obţinute ===== | + | ===== Results Obtained ===== |
| - | <note tip> | + | During the operation of the project, the current value generated by the potentiometer, which simulates the current from an electrochemical test strip, is read through the Arduino’s analog input pin. Based on this current, the code calculates the estimated glucose concentration and displays it on the 1602 LCD screen. |

| - | ===== Concluzii ===== | + | According to the calculated glucose level, RGB LEDs are controlled via PWM signals to indicate different glycemic states: |
| + | * For values below 100 mg/dL, yellow LEDs light up, indicating hypoglycemia. | ||
| + | * For values between 100 and 150 mg/dL, green LEDs are active, indicating a normal level. | ||
| + | * For values above 150 mg/dL, red LEDs turn on, signaling hyperglycemia. | ||
| + | |||
| + | These results were validated through manual testing by adjusting the potentiometer and observing the corresponding changes on the display and LED intensity, confirming the correct operation of the system in simulating glucose measurement. | ||
| + | |||
| + | The system responds quickly to changes in current and provides a clear user interface through the LCD display and visual LED indicators. | ||

| + | ===== Conclusion ===== | ||
| This project successfully demonstrates a basic but functional glucometer built with Arduino. By simulating the sensor signal with a potentiometer and using an operational amplifier, we were able to measure small currents and convert them into glucose levels. The system provides clear feedback through an LCD display and colored LEDs, offering both visual and numerical information to the user. | This project successfully demonstrates a basic but functional glucometer built with Arduino.
