TASK 4
ULTRASONIC SENSOR
The objective of the task is with the help of HC-SR04 Ultrasonic Distance Sensor (which is used for detecting the distance to an object using)we should construct an obstacle avoiding vehicle combining the distance sensing capability of the ultrasonic sensor with the motor control of the DC motor(s), the vehicle can autonomously detect obstacles in its path and navigate around them.
Materials Required :
- Arduino Board
- Ultrasonic sensors
- DC gear motors
- Motor Driver
The vehicle is equipped with an ultrasonic sensor, typically mounted on the fron eft and right side of the vehicle and Two DC motors responsible for controlling its movement.
The ultrasonic sensor emits ultrasonic waves, which travel in the air and bounce back when they encounter an obstacle. The sensor measures the time it takes for the waves to return after being emitted.
By calculating the time taken for the waves to return, the sensor determines the distance between the vehicle and the obstacle in its path.

LM35 TEMPARATURE SENSOR :
LM35 is a temperature measuring device having an analog output voltage proportional to the temperature. It provides output voltage in Centigrade (Celsius). It does not require any external calibration circuitry. The sensitivity of LM35 is 10 mV/degree Celsius. As temperature increases, output voltage also increases.
