- Smart Assistive Stick for Visually Impaired Individuals
1️⃣ LCD (16x2) Display
2️⃣ Ultrasonic Sensor (HC-SR04)
3️⃣ LDR Sensor (Light Dependent Resistor)
4️⃣ LED
5️⃣ Buzzer
6️⃣ SOS Button
7️⃣ Power Supply
1️⃣ ADC
2️⃣ Input/Output
3️⃣ Interrupt
4️⃣ UART
The ATmega2560 continuously reads input signals from the ultrasonic sensor, LDR, and SOS button.
- When the LDR detects darkness (low voltage output), the LED automatically turns ON.
- When the SOS button is pressed, the buzzer activates to alert nearby people.
- The LCD displays the real-time status of the LED and buzzer.
- This integration of sensors and output peripherals provides an intelligent, responsive, and power-efficient assistive solution.
