| - | Battery Monitoring (ADC): The code reads the analog signal from a voltage divider connected to the 7.4V battery pack. It converts this signal into a human-readable voltage value (e.g., 8.2V) and displays it on the first line of the LCD. This allows the user to monitor battery health in real-time. | + | Battery Monitoring (ADC): The code reads the analog signal from a voltage divider connected to the 7.4V battery pack.

| - | Manual Speed Selection (ADC): The code monitors the position of the slide potentiometer. It divides the slider's physical travel into four equal segments, representing "Speed 1" through "Speed 4." | + | Manual Speed Selection (ADC): The code monitors the position of the slide potentiometer. It divides the slider's physical travel into four equal segments, representing "Speed 1" through "Speed 4." |
| - | Motor Power Regulation (PWM): Based on the selected speed level, the Arduino generates a Pulse Width Modulation (PWM) signal on Pin 9. This signal controls the MOSFET, which acts as a high-speed switch to regulate the motor's rotation. The code is calibrated so that "Speed 4" provides just enough power to reach the target of 2400 RPM without overstressing the 3D-printed arm. | + | Motor Power Regulation (PWM): Based on the selected speed level, the Arduino generates a Pulse Width Modulation (PWM) signal on Pin 9.

| - | Visual Feedback (I2C): On the second line of the LCD, the code displays the current speed level (1–4) and a visual progress bar. It uses the I2C communication protocol to send this data to the display using only two wires, keeping the wiring clean. | + | Visual Feedback (I2C): On the second line of the LCD, the code displays the current speed level (1–4) and a visual progress bar.

| - | Safety & Stability: By using discrete speed steps instead of a raw slider value, the code ensures the motor maintains a steady RPM for each setting, which is vital for maintaining a stable, undistorted POV image. | + | |
