This project uses an HC-SR04 ultrasonic sensor and Arduino UNO to measure the distance of objects in both centimeters and inches. The measured data is displayed on an I2C LCD. The project was ...

Step 5: Assembling The Components. Even though we are using only the transmitter of one ultrasonic sensor and the receiver of the other, but it is mandatory to connect all of the four pins of the ...

Buy arduino, buy sound shield, buy distance sensor shield, plug into each other, burn example code, stuff components inside box. Not only is this not a hack but he might as well have just bought a ...

You only need to use the famous speed formula: Where s is speed, d the time traveled and t is time. If we clear the space, it would be as follows. d = s x t. The value of speed is known to us as the ...

Project Hardware Software Selection. I have used the Raspberry Pi Pico because it is a very small, low cost microcontroller board. Also, this board is much faster than any other small microcontroller ...

•An Ultrasonic sensor and a 16X2 LCD display were interfaced using Arduino Uno R3 Microcontroller to measure the distance from the sensor to an obstacle placed in front of it.•The LiquidCrystal.h ...
