1. What percentage of deaf and dumb people live in India?
20% of the world's deaf and dumb people reside in India, totaling 2.4 million individuals. This significant population faces communication challenges due to their inability to speak or hear. The lack of communication is a primary issue for these individuals, as they rely on sign language as their primary means of communication. Sign language, a formal language using hand gestures, plays a crucial role in facilitating communication for the deaf and dumb community. Recognizing the importance of addressing this communication gap, researchers have developed specialized applications, such as an ideal Interpreter, to convert hand movements into visual and audible forms. These applications aim to bridge the communication divide and provide a more inclusive environment for deaf and dumb individuals in India.

2. How does the Arduino Mega Microcontroller process analogue voltage from flex sensors?
The Arduino Mega Microcontroller processes analogue voltage from flex sensors by receiving the analogue voltage through its ADC input pins. The analogue value is then converted into matching digital values and stored in the microcontroller's memory. The voltage value is recognized as input if it exceeds the threshold value. This process allows the microcontroller to detect hand movements and convert them into digital signals for further processing and output display on a mobile device's screen and speaker.
