Arduino Tutorial: Interface Arduino Pro Mini and Ultrasonic Sensor
The Arduino Pro Mini is a compact, versatile microcontroller board that is widely used in various projects, especially those where space is a constraint. One of the most commonly used sensors in Arduino projects is the ultrasonic sensor, which can measure distances using sound waves. In this tutorial, we will explore how to interface the Arduino Pro Mini with an ultrasonic sensor and create a simple distance measuring system. Requirements: To follow along with this tutorial, you will need the following components: Arduino Pro Mini board Ultrasonic sensor (HC-SR04 or similar) Jumper wires Breadboard (optional, but recommended) Connect the Arduino Pro Mini The Arduino Pro Mini has a minimal number of pins, so we need to make sure to connect the sensor to the correct pins. Here's how to do it: Connect the VCC pin of the ultrasonic sensor to the VCC pin (5V) of the Arduino Pro Mini. Connect the GND pin of the ultrasonic sensor to the GND pin of the Arduino Pro Mini. Connect the TRIG pi...
