The automatic smooth braking system for a four-wheel vehicle. Ultrasonic sensors are placed at the front and rear of the vehicle to detect obstacles. When the front sensor detects an obstacle, the system smoothly stops the vehicle, activates an alarm, and turns on light indicators. The rear sensor detects obstacles behind the vehicle and triggers a red-light indication as a warning. The distance of obstacles is displayed in real-time on an LCD screen. The main controlling device of the project is PIC Microcontroller. To achieve this task microcontroller loaded program written in Embedded C language

  The main objectives of the project are:

• To design an automatic braking system for a four-wheel vehicle using ultrasonic sensors for obstacle detection.
• To provide real-time obstacle distance display on an LCD screen for user awareness.
• To enhance vehicle safety by activating alarms and light indicators during obstacle detection.

  The major building blocks of the project are:  

1. Regulated Power Supply.
2. PIC Microcontroller.
3. DC motors with driver.
4. LCD display.
5. Buzzer.
6. SR04 Ultrasonic sensors.
7. Crystal oscillator.
8. Reset.
9. LED indicators.
10. Battery.

  Software’s used:  

1. PIC-C compiler for Embedded C programming.
2. PIC kit 2 programmer for dumping code into Micro controller.
3. Express SCH for Circuit design.
