Arduino With Ultrasonic Sensor and Temperature Sensor

Lets see how the connection are made between Arduino with ultrasonic sensor and temperature sensor

1.Arduino UNO

2.Ultrasonic Sensor (HCSR034)

3.Temperature sensor (DS18B20)

Connect the power and ground of sensors with Arduino

For Ultrasonic sensor :

echo_Pin - digital pin 2
trig_Pin - digital pin 3

For Temperature sensor :

ONE_WIRE_BUS_PIN - digital pin 4
